Dosing equipment. Equipment for dosing, bottling, packaging and packaging of finished products

Dosing- measurement of the amount of a substance by determining its mass or volume or by recalculating identical piece products. According to the structure of the working cycle, dosing can be continuous or discrete, and according to the operating principle - volumetric or weight. Continuous volumetric dispensers deliver the product in a uniform flow; in this case, the volume of product supplied per unit time is determined by the feed rate or cross-sectional area of the product flow. With a constant flow cross-section, special drive mechanisms are installed in the dosing devices to regulate the product flow rate within the required limits. In the second option, dosing devices are equipped with mechanisms for changing the flow of the supplied product during its movement.

In continuous weighing, the flow of material leaving the feeder is continuously weighed and the feeder capacity is continually adjusted based on the results.

Discrete dosing consists of periodically repeating cycles of measuring the dose of the product and submitting it for packaging. In the discrete volumetric method, dosing equipment measures a portion, usually using a measuring chamber of a given volume. Discrete weight dosing is based on measuring a dose of a certain mass.

The variety of structural and mechanical properties of packaged products determines the specificity of the designs of dosing devices.

Currently, serial dispensers as separate components of a production line are practically not developed or manufactured. The exception is volumetric and weight dispensers for packaging products in large containers (bags, barrels, tanks, etc.), as well as weigh dispensers for bulk products.

For dosing bulk food products into large containers (bags and packages) at processing plants, weighing dispensers are widely used.

Automatic equal-arm dispensers of type D and DM are the simplest in design. They do not have a drive and operate only under the influence of the mass of weights placed in the weight holder and the mass of the product entering the load receptor by gravity.

The main components of this type of dispensers are: a frame with an automatic mechanism, a rocker arm, a load receptor, a weight holder, a regulator, a casing and a counter.

Double equal-arm rocker 2 (Fig. 9.1) of the dispenser with two prisms placed on cushions mounted on brackets 4 beds. A weight holder is suspended on the load-receiving prisms of the left arm of the rocker arm 1, inside which weights are installed. The weight holder has a cavity into which an additional weight is placed to calibrate the dispenser, i.e., to bring the unloaded dispenser into a state of equilibrium. A load receptor is suspended on the load-receiving prisms of the right arm of the rocker 13 with opening bottom 14.

The inlet funnel is closed by a sector damper 11, which interacts through a system of levers 6, 7, 8 And 18 with a locking mechanism for the load receptor, and through a spring 10 the suspension is maintained open by the cam of the load receptor. Spring 10 can be pulled out of contact with the cam by a rod. To protect against dust and to avoid possible splashing of the product during operation of the dispenser, the inlet funnel is equipped with an additional casing, which

A release lever 5 is installed on the frame, holding the lever system 6,7, 8 And 18 from falling.

The bottom of the load receptor is locked after closing with a lever system 15 and knee 16 shutter The load receptor is equipped with a locking lever 17, which does not allow you to open the bottom 14 until the lever system moves and the damper is completely closed, and also prevents the damper from opening until the bottom is completely closed 14.

A regulator is installed on a pin mounted on the frame 3 accuracy of plumb lines. The end part acts on the bracket 12, which is attached to the load receiving device. The meter is connected through a rod to the damper 11, which, when triggered, sets it in motion.

The dispenser works as follows. When the damper is closed, the lever system of the automatic mechanism is in the upper position, and the suspension spring is relaxed. As the product is filled, the load receptor lowers and the rod and spring 10 moves down. Damper 11 closes as the roller 9 vertical lever 7 is fixed on the release lever pin 5. At the same time, she rests her finger on the adjusting screw of the right lever 8, stops and takes the filling position. The product enters the load receptor through a narrow gap between the valve and the funnel.

After reaching the specified mass, the bolt on the bracket 12 presses the release lever 5, turning it clockwise. At the same time, the finger is on the lever 5 comes out from under the roller 9 vertical lever 7, the lever system moves, the levers 6 And 8 occupy a horizontal position. The flap closes, the knockout lever 18 turns counterclockwise and acts on the knee shaft with the right end 16, lifting the shutter. Bottom 14 is released and opens under the influence of the mass of the product. The load receptor is unloaded, after which the rocker arm rotates counterclockwise under the weight of the weight holder, the load receptor moves upward, compressing the spring 10 damper rod. Bottom closes, knee rod 16 the bolt acts on the right end of the knockout lever 18 and moves the entire system of levers and the associated damper. Spring 10 the rod unclenches and fully opens the damper. Leverage 6, 7, 8 and 18 returns to the upper position, release lever 5 under the influence of its heavier left part and the grip located on the vertical lever, it returns to its original position and is fixed with a finger under the roller of the vertical lever 7.

The damper, connected by a rod to the counter for the number of plumb lines, opens and causes the counter to register the plumb line. Then the dosing cycle is repeated again.

carried out manually.

The 2PPM-ZM weighing dispenser is designed for automatic dosing of flour in portions of a certain mass, followed by filling the weighed portions into bags, which are placed manually under the outlet of the dosing hopper. Subsequent packaging operations (sealing and sealing of bags) also

The dispenser frame is made in the form of two walls and two sidewalls, fixed to the stand. The walls are connected at the top by a feeder funnel 5 (Fig. 9.2). Two brackets with agate cushions are installed on them, onto which a double equal-armed rocker arms are attached by supporting prisms 4. Right front

The rocker arm is equipped with a balance indicator. A load receptor is suspended on the front prisms of the rocker arm 2 with a hinged bottom that is held in the closed position by a latch. To protect the dispenser mechanism from flour dust, the load receiving device is placed in the dosing hopper, and the racks with supports on which this device is suspended are moved outside. A weight holder is suspended on the rear prisms of the rocker arm 3, at the base of which there is a cavity for additional weight used when calibrating an unloaded dispenser.

On the top cover of the weight holder, working weights are placed in special sockets. Based on weight holder 3 a height-adjustable rod is placed, which interacts with the precision regulator spring. A height-adjustable pin is placed on the traverse of the weight holder, which fixes the extreme lower position of the load receptor. To protect against swinging, the load receptor and weight holder are equipped with strings.

A plate is fixed between the walls and sides of the frame, on which there are two contact boxes that serve to control the internal and external dampers. A smoothness regulator and a level are also installed on the stove.

Hanging hopper 1, in which the load receiving device is located 2, attached to the front wall of the frame. The lower, easily removable part of the hopper is made in the form of a cone with a neck and is used for putting on the bag.

The dispenser feeder is a cone-shaped funnel with a cylindrical neck, equipped with two sector dampers: internal and external. The internal flap has a width-adjustable window through which the product is added during dosing. An over-dispensing hopper is connected to the feeder funnel through a gravity pipe 6, to which communications are connected to feed the dispenser with flour. The dispenser hopper and funnel are equipped with special leavening agents, which ensure constant density and uniform flow of flour through the neck of the funnel and dispenser during operation of the dispenser.

The electric motor with gearbox is mounted on a swinging plate equipped with a tension device and installed between the sidewalls of the frame on a stand 11.

A two-position weight dispenser DMAK-05 (Fig. 9.3) is part of the production line and is designed for packing equal portions of short-cut and stamped pasta into bags when working together with a molding machine. The dispenser consists of two identical weighing devices that alternately measure a given portion of the product and unload it onto the product line for delivery into consumer containers (packs or boxes) placed on the operating rotor of the filling machine.

The weighing device 7 includes a receiving hopper 5, vibrating coarse feeders 3 and precise dosing 4, weigh hopper 2 and lever weight meter 6.

Pasta is fed into the weighing bin 2 first weighing device from the receiving hopper 5 first with both vibrating chutes 3 And 4, and at the end of dose measurement only with a vibrating tray 4. The measured dose is poured onto the product line 1 for transfer to packaging. A similar process is followed

in the second weighing device, which makes it possible to alternately unload measured doses from both weighing devices.

For volumetric dosing of liquid products into large containers, dosing pumps are used.

In a plunger metering pump, when the plunger moves 2 (Fig. 9.4, A) pump to the right in the working chamber 4 a vacuum is created, liquid through the suction valve 1 fills the working chamber. When the piston moves to the left, the suction valve 1 closes, plunger 2 presses on the liquid in the working chamber and it flows through the discharge valve 2 is forced into the discharge pipeline. The plunger is driven by a crank 7 or an eccentric mechanism through a shield 6. Oil seal 5 prevents the product from leaking out.

Gear metering pump (Fig. 9.4, b) has two gears. The rotor gear 2, connected to the working shaft (rotor), receives rotation from the electric motor, the other, the closing gear 5, is free and is driven by the first gear.

The rotor, rotating clockwise, transmits movement to the contactor. When the gear teeth disengage, a vacuum is created and fluid is sucked through the pipe 1 into the body 3. Gears capture fluid and move it in the direction of rotation. When the teeth re-engage in the discharge area 4, the liquid located in the cavities between the teeth and the walls of the housing is forced into the discharge pipeline.

Dosing is one of the most important operations in the technological process of producing bread products. The main purpose of dosing devices is to provide a given amount of material by mass (or maintain a given component flow rate) with a certain accuracy.

Basic requirements for weighing dispensers (flour dispenser):

Dosing accuracy;

High performance;

Simplicity of design and reliable operation of the dispenser components and its control system;

The ability to create automatic complexes that allow mixing dough semi-finished products according to a given technological program.

Automatic dispensers can be divided into continuous and batch dispensers. In turn, they can be divided into dispensers: working on a weight and volume principle.

Batch dosing is characterized by periodic repetition of the component dose release cycle (flour dispenser). With the portioned volumetric method, the dispenser usually measures a portion using a measuring chamber of a given volume. Portion weight dosing is based on measuring a dose of a certain mass. With continuous volumetric dosing, the doser delivers a flow of material at a predetermined volumetric flow rate.

The weight dosing method ensures high accuracy, therefore, for dosing the main component of the dough - flour, both for continuous and portioned dough preparation, a weighed flour dispenser is often used.

The volumetric dosing principle is structurally simpler, therefore weighing dispensers based on this operating principle are more reliable. The use of the volumetric method significantly simplifies the process of dosing liquid components. At the same time, volumetric dosing is often characterized by a more significant error, which in some cases limits its use.

The baking industry uses systematic dosing of several different types of raw materials, so it is more rational to use multi-component dosing devices.

Multicomponent dosing can be carried out according to the following schemes:

Consecutive dosing of components in a common dispenser;

Parallel dosing of each component in a separate special dispenser.

Sequential dosing is used for batch dough preparation and is very simple and economical. It provides less metal consumption and compact installation. However, the duration of the overall dosing cycle is long due to the sequential measuring of components. This may reduce the performance of the dough making equipment.

Parallel dosing is used for continuous and batch mixing of semi-finished products. It allows each weighing dispenser to be more fully adapted to the characteristics of the component being dosed and, thereby, increasing the dosing accuracy. At the same time, it must be taken into account that dosing stations of this type are more bulky and more expensive.

Each dosing unit is unique equipment and is manufactured taking into account the specifics of the Customer’s activities. When selecting the optimal modification and configuration, our competent managers take into account all factors: the characteristics of the packaged product (its consistency, fragility, fluidity, abrasiveness and other properties), the required productivity, the dimensions of the production facility and a number of others.

The line of mechanical dispensers is represented by compact manual devices, which will be the optimal solution for small, small-scale production (MDR pneumatic dispenser, MD-500T manual tablet press). Despite the low productivity, the installations are distinguished by wide functionality and the ability to be equipped with additional devices (Manual mechanical dispenser MDR with a mixing device).

The group of semi-automatic peristaltic dosers is represented by a wide range of models with different capacities and additional options: Peristaltic dosing pump MDP-200M, Peristaltic dosing pump MDP-200D, Peristaltic dosing pump MDP-200 Mini and a number of others. The special design of the dosing head eliminates the occurrence of pulsation, vibration and vortex phenomena, which is especially important when packaging products with a complex structure (pharmaceutical solutions, suspensions, chemical products, pesticides).

Automatic peristaltic dispensers are larger units equipped with conveyors for easy movement of containers and sensors that detect the presence of a bottle at the filling position. The equipment is distinguished by a wide variety of additional functions: Dosing unit with simultaneous supply of two types of liquids MDP-200L, Peristaltic unit MDP-200L with six nozzles and a loading table, Dosing unit with 12 dosing heads, a loading table and a dividing disk MDP-200L.

The range of manufactured and supplied semi-automatic piston dispensers includes both standard installations (Semi-automatic tabletop piston dispenser MD-500D5), and with a heating jacket (Piston dispenser MD-500M1 with heating jacket), a mixing device (Semi-automatic volumetric piston dispenser MD-500M1 with a stirrer) and other capabilities (Semi-automatic filling machine MD-500M1 with product intake function, Piston semi-automatic hot filling metering pump MD-500D3). Installations of this type are presented in tabletop and floor-standing versions.

The dosing device in automatic piston units is made in the form of a piston pump with volumetric control and is equipped with a system that ensures that the container is filled with product without residue (without the “last drop” effect). The equipment can be equipped with a storage table (Automatic piston dispenser MD-500D2M), a mobile platform for quick installation of the dispenser on site (Automatic filling machine MD-500D2P) and other modifications.

Automatic linear piston dosers belong to the category of the most high-performance dosing units presented in our catalog. For the dosed supply of liquid and paste-like products in large industries, an automatic linear piston dispenser MD-500DL has been developed with the ability to fill highly viscous liquids (100% glycerol and thicker). The automatic dispenser for thick products BR-100 and the automatic filling machine MD-500D2P provide effective dosing of thick and foaming products. These models can be equipped with product counting and rejection systems.

Lines of screw and volumetric dispensers have been developed specifically for packaging thick, bulk and granular food products (milk powder, seasonings, starch), household chemicals (washing powders, cleaning products), cosmetics and pharmaceuticals in powder form. The installations are adapted to work with complex products that are prone to sticking, thanks to the design being equipped with special agitators that capture the entire surface of the loading hopper (Semi-automatic dispenser for packaging bulk products, powders MD-500P3, screw dispenser (weight/volume) MDSh-600).

The design capabilities of our dosing machines allow us to implement the process of packing the product into various types of containers (bottles, bottles, jars, bags, etc.), which is achieved through readjustment (replacing equipment). Such broad versatility allows manufacturers to launch new products without purchasing additional packaging equipment. The result of the implementation of dosing units produced by AURORA PACK ENGINEERING is a reduction in the workload on personnel, minimization of packaging costs and an increase in production volumes.
