Description

The utility model relates to devices for volumetric dosing of a multicomponent mixture in the food industry, for example, for the preparation of salads according to individual orders of consumers at catering establishments. The device can also be used in agriculture for the preparation of animal feed.

A doser of bulk materials is known (Patent for utility model RU 133290 U1, IPC G01F 13/00, priority 05.24.2013, published 10.10.2013) containing a hopper, a screw with a shaft located in the casing, an unloading window. A known utility model is for dispensing a single component. A disadvantage of the known dispenser is the impossibility of compiling a multicomponent mixture, which directly follows from the presence of one hopper and one screw.

A well-known feed mixer (Patent for invention RU 2325097 C2, IPC A23N 17/00, priority March 28, 2006, published May 27, 2008) containing a casing with an auger installed inside it, a feed hopper divided into sections by vertical partitions with dispensers in the lower part of each section . A known device prodolzhaet mixing several bulk components and doses the resulting mixture. A disadvantage of the known device is the inability to perform accurate volumetric dosing of large pieces of food components intended for human nutrition.

The known module of discrete weight microdosing (patent for invention RU 2168706 C2, IPC ⁷ G01F 13/00, G01G 13/00, priority 10.08.1999, published 10.06.2001) containing a frame with mounted bins, a feed mechanism with drives, a control unit , trays, weight sensors. The known device is intended for the formation of a multicomponent mixture of bulk materials in the pharmaceutical industry and for the preparation of feed in agriculture. A disadvantage of the known device is the inability to perform bulk dosing of large pieces of food components intended for human nutrition.

The closest analogue to the claimed utility model for the maximum coincidence of similar features is a device for implementing the method of dosed feeding a multicomponent mixture (USSR author's certificate SU 1377593 A1, G01F 13/00, priority 27.06.85, published 02.29.88) containing hoppers for finely divided dry components , under each of which a feeder with a drive and a weight batcher with a shut-off element in the outlet pipe are sequentially placed, a distributor located under the weight batchers, sensors of the weight batchers connected to the information inputs of the control unit, the drives of the feeders and locking elements connected to the outputs of the control unit. The hoppers with feeders are located in a circle relative to the distribution element mounted in the center and connected to the rotation drive.

A disadvantage of the known device is the impossibility of volumetric dosing of components of different state of aggregation, for example, the preparation of a mixture of piece pieces of vegetables or fruits, chopped lettuce, with the addition of liquid or pasty components of vegetable oil, mayonnaise and other spices.

The objective of the claimed utility model is to increase the accuracy of dosing a multicomponent mixture of ingredients of different sizes and different state of aggregation.

The proposed device volumetric dosing multicomponent mixture contains a number of features common with the closest analogue (prototype). The device contains bins for loading the initial finely divided components, for example, finely chopped lettuce leaves, etc. Under the hoppers for finely chopped components, screw feeders with drives are located. A weight batcher and a weight batcher sensor connected to one of the information inputs of the control unit are installed in the area of the outlet nozzles of the screw feeders. For the accumulation and intermediate storage of components, an intermediate drive is introduced into the device. General management of the work is carried out by the control device, which has several information inputs and several outputs. The signals of the sensors are connected to the information inputs of the control device, and the drives of the nodes are connected to the outputs of the control device.

The difference between the claimed utility model and the known device is that additional hoppers and feeders are added to the device, which are divided into several groups according to their functional purpose: 1) hoppers and feeders for large lumpy components, for example, pieces of fruits and vegetables, 2) containers and dispensers for liquid components, for example, vegetable oil, etc., 3) hoppers and dispensers for pasty components, for example, mayonnaise, sour cream, etc. The execution form of the hoppers and feeders of each group takes into account the aggregate melting of the dosed component.

In the lower part of each hopper, in front of the entrance windows of the screw feeders, component dispensers are installed, a specific execution form for each functional group, depending on the state of aggregation of the component.

Dispensers of large piece components are made in the form of vane volume dispensers, the volume of the cavity between two adjacent blades corresponding to the placement of one piece of component. The dispenser of lumpy components has a rotation drive at a predetermined angle, connected to one of the outputs of the control device.

Dispensers of finely dispersed mixture are made in the form of a vertical screw and perform two functions - accelerated flow and destruction of the arch. Dispenser drives are connected to the outputs of the control device.

Dispensers of liquid components are made in the form of liquid dispensers with electromagnetic valves and flow meters. Measurement of the volume of liquid can be made by time, or by the readings of the flow meter. The dosing process is controlled by electromagnetic valves connected to the outputs of the control panel.

Dispensers of pasty components are made in the form of piston volumetric dispensers, which contain inlet and outlet valves, a displacement drive and a piston displacement sensor. Dosing involves two stages: filling the internal volume of the dispenser through the inlet valve with simultaneous movement of the piston by a predetermined amount, unloading the dispenser through the exhaust valve by moving the piston to its original state. The amount of movement is recorded by the displacement sensor. The displacement sensor is connected to one of the information inputs of the control device. The movement drive is connected to one of the outputs of the control device.

At each outlet pipe of the lump components, optoelectronic sensors are installed that perform the function of counting the lumps. The outputs of the optoelectronic sensors are connected to the information inputs of the control device. The counter of large pieces is an integral part of the control device and can be made either in the form of a separate electronic unit inside the control device, or can be implemented programmatically in the general program for controlling the device.

At the output of the finely dispersed component feeders, a weight batcher is installed that is identical to the known prototype weight batcher. Weight measurement is based on the readings of the weight sensor connected to the information inputs of the control device.

The shape and geometric dimensions of the feeders are made different for each functional group of components.

Feeders of lumpy components are made in the form of a screw. The radius of the screw part and the pitch of the screw of the screw are made with the possibility of moving one piece of the component in one revolution. The screw pitch of the screw is equal to the distance between the outer edges of the blades of the blade volumetric batcher. The action of the paddle feeder and screw feeder is synchronized in time. Drives for rotating the axes of the screw and blade volumetric feeder are made on the basis of stepper motors. Control is carried out by supplying a given number of current pulses from the control panel to the motor windings. The indicated sequence of actions eliminates jamming and destruction of large pieces when they fall between the walls of the feeder housing and the screw surface of the screw.

The finely dispersed mixture feeders are made in the form of a screw with a minimum clearance between the screw part and the housing wall. Feeders perform the function of loading a given weight of a finely divided component. The weight is determined by the readings of the weight meter sensor. When the set weight is reached, the control panel stops the rotation of the axis of the screw feeder.

The liquid component feeders are made in the form of a flexible tube.

The group of pasty components does not contain separate feeders, so the material enters the intermediate storage directly from the piston batcher.

Various components of the mixture are loaded into the intermediate drive, which is mounted on a rotating table and, with the help of the drive, moves sequentially under the output branch pipes of the feeders. The control panel is based on a microprocessor. The composition of the finished mixture and the sequence of actions of the mechanisms is set by software.

The combination of features of the utility model allows to obtain a technical effect in the form of increasing the accuracy of dosing of each component of a different state of aggregation separately and the accuracy of adherence to the formulation of the multicomponent mixture as a whole. An additional technical effect is the reduction in the share of manual labor at the cooking site, the expansion of the assortment of dishes, the possibility of performing salads on individual orders, for example, the ability to exclude individual components that cause allergies in a particular client.

The relative position of the elements (shown in Fig. 2) is as follows. A rotary table 15 is mounted in the center of the device for rotation about an axis. The intermediate drive 14 is shifted to the edge of the rotating table 15. In the upper part above the surface of the rotating table around the circle there are successively bunkers of coarse-grained components 1, blade volumetric batchers 2, feeders of coarse-grained components 3, optoelectronic sensors 4, bins of finely dispersed component 5, dispensers of finely dispersed component 6, finely dispersed component feeders 7, weight batcher 8, containers for liquid component 9, liquid bulk dispensers 10, pasty component hoppers 11, volumetric orshnevye dispensers 12.

Fine-dispersed components in the form of finely chopped green leaves are loaded into the bins 5. Liquid components, for example, vegetable oil of different varieties, are loaded into containers 9. Paste-like components, such as sour cream, mayonnaise or other sauce is loaded into the bunkers 11. After starting up, the control device generates a command to drive the table 16, which rotates the rotary table 15. The rotary table 15 moves p intermediate drive 14 into the area of the first discharge pipe of the feeders of lumpy components 3. The rotary table 15 stops. The blade volumetric dispenser 2 begins to move and moves the pieces of the component to the feeder 3. The feeder 3 is set in motion and moves the pieces of the product into the discharge nozzle of the feeder. Pieces of material fall down. At this moment, the optoelectronic sensor 4 generates counting pulses of the pieces, which are transmitted to the information input of the control device 13. After reaching the set value of the counting pulses, the blade volumetric dispenser 2 and the feeder 3 are stopped. The rotary table 15 at the command of the control device 13 is again set in motion and moves under the discharge pipe of the next feeder. After loading all the coarse-grained components into the intermediate drive, the intermediate drive 14 moves into the range of the fine component feeder 5. The control device drives the fine component dispenser 6 and the fine component feeder 7.

All finely dispersed components are loaded in turn into a weighing batcher 8, which registers the weight of the loaded component and transmits a signal to the information input of the control device 13. Upon reaching the set weight, batchers 6 and feeders 7 stop. The rotary table 15 again moves and moves the intermediate accumulator 14 into the coverage area of the liquid volumetric dispensers 10. The liquid volumetric dispensers 10 are set in motion by the command of the control device 13 and direct a predetermined volume of the liquid component to the intermediate accumulator 14. After the loading of the liquid component is completed, the rotary table 15 is set in motion and moves the intermediate accumulator 14 into the coverage area of the volumetric piston dispensers 12, which are activated by the command of the control device 13 and send a predetermined amount of the pasty component to the intermediate accumulator 14. After completing all the specified operations, the rotary table 15 moves the intermediate drive 14 into the unloading zone of the finished mixture and stops. The control device 13 generates a ready signal for the multicomponent mixture.

Using the utility model will increase the accuracy of dosing of each component of a different state of aggregation separately and the accuracy of adherence to the recipe of the mixture as a whole, reduce the proportion of manual labor, increase the range of dishes, provide the opportunity to make salads for individual customer orders, in particular, eliminate components that may cause allergies to a specific client.
