Description

The proposed utility model relates to the food industry, in particular, to machines that form dough pieces by extrusion, and relates to a device for the continuous supply of food material.

The closest in technical essence and the achieved result to the proposed utility model is a dough-setting machine protected by patent for invention GB632910, publ. 12/24/46, cl. A21C 11/16, adopted for the closest analogue (prototype).

The prototype device comprises an extrusion chamber having an outlet, a valve for opening and closing the outlet, an inlet for adding dough to the extrusion chamber, a valve for opening and closing the inlet, a valve for controlling the inlet of compressed air into the extrusion chamber and discharge pressure, as well as means to control the level of the test in the extrusion chamber and automation to control and synchronize the operation of all valves.

The advantages and common features of the prototype with the proposed utility model is the supply of food material under the action of compressed air, with a stable flow rate, by maintaining a constant product level in the extrusion chamber.

However, at the same time, the device described as a prototype has a significant drawback - the operation of the device is periodic, to load a new portion of the product into the extrusion chamber, it is necessary to stop operation and bleed air, which complicates the use of the device, reduces its performance and increases marriage.

The objective of the proposed utility model is the improvement of the device for the continuous supply of food material.

The technical result from the use of a utility model is to increase productivity, usability, reduce marriage.

This object is achieved in that in a device for the continuous supply of food material containing an extrusion chamber, an inlet valve, an outlet valve, a compressed air supply valve to the extrusion chamber, a material level control sensor, a sluice chamber with a loading valve and a compressed air supply valve is made in front of the inlet valve in the airlock, and in front of the airlock there is a batch feed mechanism; the inlet valve and the loading valve contain a cylindrical spool with an internal cavity in volume exceeding the portion of food material transmitted through the lock chamber; the inlet valve and the loading valve are made of a rotary type; the inlet valve and the loading valve are made of a slide type; the batch feeding mechanism consists of two triangular synchronously rotating knives.

Figure 1 shows a cross-sectional drawing of a device for continuous supply of food material.

Figure 2 shows a longitudinal section of a drawing of a device for continuous supply of food material.

Figure 3 shows a diagram of the operating procedure of the device for the continuous supply of food material.

Structurally, the proposed device for the continuous supply of food material in figures 1-3 contains:

1 - extrusion chamber;

2 - inlet valve;

3 - inlet valve spool;

4 - output valve;

5 - valve for supplying compressed air to the extrusion chamber;

6 - sensor for monitoring the level of material;

7 - airlock chamber;

8 - loading valve;

9 - spool of the loading valve;

10 - valve for supplying compressed air to the lock chamber;

11 - portioning mechanism.

In front of the inlet valve 2, a lock chamber 7 is made with a loading valve 8 and a valve for supplying compressed air to the lock chamber 10, and a batch feed mechanism 11 is installed in front of the lock chamber 7.

The inlet valve 2 and the loading valve 8 contain cylindrical spools 3, 9 with an internal cavity exceeding in volume the portion of food material transmitted through the lock chamber 10.

The inlet valve 2 and the loading valve 8 are made, for example, of a rotary type.

The inlet valve 2 and the loading valve 8 are made, for example, of a slide type.

The batch feed mechanism 11 consists of two triangular synchronously rotating knives.

The proposed utility model works as follows.

Figure 3 a, b. From the extrusion chamber 1, part of the food material under the action of compressed air through the outlet valve 3 enters the batch feed mechanism 11. In the extrusion chamber 1, the excess pressure of the compressed air is maintained, and in the airlock 6, atmospheric pressure. When lowering the level of food material in the extrusion chamber 1, the material level control sensor 6 is activated, the triangular knives in the batch feeding mechanism 11 rotate 120 degrees and the measured portion of the food material falls into the spool 9 of the loading valve 8 of the lock chamber 7.

Figure 3 c. The spool 9 of the loading valve 7 rotates 360 degrees, while the food material falls from the spool 9 of the loading valve 8 into the spool 3 of the inlet valve 2 of the extrusion chamber 6. In the extrusion chamber 1, an excess pressure of compressed air is maintained, and in the airlock, atmospheric pressure is maintained.

Figure 3, In the lock chamber 7 through the valve for supplying compressed air to the lock chamber 10 serves compressed air. In this case, the pressure in the extrusion chamber 1 and in the lock chamber 7 is equalized. The inlet valve 2 is rotated 360 degrees and the food material falls from the spool 3 of the inlet valve 2 into the extrusion chamber 1.

Upon completion of the rotation of the inlet valve 2 through the valve for supplying compressed air to the lock chamber 10, the pressure in the lock chamber 7 is released. The lock chamber 7 goes into the initial position, similar to the position in Fig. 3 a.

The design of the device for the continuous supply of food material provides a replenishment of the amount of food material in the extrusion chamber without stopping the operation of the device, which contributes to an increase in productivity, ease of use, reduction of marriage.
