Brief Description of the Drawings

The drawing shows a General view of a universal tank for processing and preparing liquid food products.

The implementation of the invention

The universal tank consists of a housing with an inter-wall space 1, nozzles for supplying 2 and removal of heat carrier 3 (hot or cold water). A combined drive 5 of the mixer 6 is mounted on the cover 4, which in turn consists of blades 7 and a helicoid 8, a hatch with a viewing window 9. A drive shaft 10 is mounted in the cover 4, through a coupling 11 with a mixer 6. The cover 4 is blocked by a limit switch 12 s agitator drive 5.

The blades 7 of the mixer 6 are equipped with shock absorbers 13, hollow shafts with flushing holes 14 of the helicoid 8 connected to the flushing manifold 15 using the stuffing box 16. Spray nozzles 17 are mounted in the flushing manifold 15.

The filling pipe 18 for filling the tank with the processed product has an expanded part, which is introduced into the lower part of the housing with an interwall space 1, The pipe 19 for introducing products requiring preliminary cleaning, which is built into the filling pipe 18, is additionally equipped with a filter 20.

In the lower part of the housing with an inter-wall space 1, a device for collecting finished products is mounted, which includes a pipe 21 for draining liquids (milk, buttermilk, milk replacer, washing solution), a hatch 22 for unloading butter, mounted on a rotary bar 23.

In the casing with the inter-wall space 1, milk level sensors 24, cream 25, temperature sensors 26, as well as a tap 27 for sampling the processed product are built-in.

The control panel 28 is located on the front side of the tank body. A universal tank is mounted on four adjustable legs 29.

The universal tank in various modes works as follows:

The heat treatment of milk. The milk to be cooked is fed through the filling pipe 18 to the lower part of the universal reservoir, which, together with its expanded part at the outlet, excludes mechanical action and foaming of milk. The control of filling the working volume of the tank with milk is provided by milk level indicators 24. If necessary, the flow of the initial milk is sent through the filter 20. At the same time, the coolant is pumped through the interstitial space of the housing 1 with a temperature corresponding to the heat treatment mode (pasteurization, cooling), for which valves are opened on the supply 2 and outlet 3 nozzles.

From the remote control 28 include drive 5 of the mixer 6 in the heat treatment of milk. The design of the mixer 6 ensures uniform mixing of the entire volume of milk, which intensifies the heat transfer process between the processed product and the heat carrier located in the inter-wall space 1, which helps to reduce the heat energy consumption, and the mixing intensity (the speed of milk movement should not exceed 1 m / s) excludes changes in the structure of protein and fat fractions, while maintaining the technological suitability of milk as a raw material for dairy products.

In the process of rotation of the mixer 6, the contact of its blades 7 with the wall of the universal tank is eliminated due to the presence of shock absorbers 13 allowing to increase the resource of the tank.

Monitoring of the heat treatment modes is provided by temperature sensors 26. The processing time is regulated by technological standards.

Unloading of processed milk is carried out through the pipe 21. If necessary, sampling of the processed product is provided by means of a crane 27.

Cream ripening mode. The tank is filled with cream through the filling pipe 18 to 50% of its working volume. The cream ripening process is controlled both manually by means of the control panel 28, and in automatic mode: the set temperature in accordance with the production technology is maintained during the work cycle by periodically turning on the mixer 6 and supplying cold water. The electronic automatic control system monitors the cream preparation time, cooling and ripening temperature, cream level in the apparatus, etc. (similar to the electronic system of the capacity for ripening cream L5-OAV-6.3).

Cream whipping mode. From the remote control 28 include drive 5 of the mixer 6 in the mode of whipping cream. The speed of the cream in this mode will be 5 ... 7 m / s. The intensive action of the blades 7 and the helicoid 8 of the mixer 6 leads to a turbulent movement of the cream flow in the center of the universal reservoir, which intensifies the process of aggregation (sticking) of fat globules and the formation of oil grains.

After completion of the churning process, the formed buttermilk is discharged through the pipe 21, then the hatch 22 is opened and the oil mass is discharged into an appropriate container (pan, bath, etc.). For the convenience of the unloading process, the hatch 22 is diverted to one of the extreme positions along the rotary rod 23.

Mode of production of milk replacer. Obtained in the processes of obtaining cream (skim milk) and whipping them into butter (buttermilk) products are valuable secondary milk raw materials. Vitamins are added to them in accordance with the recipe and served in a universal tank. In accordance with the technology for the production of a substitute for whole milk (milk replacer) for young cattle, the heat treatment mode (temperature and duration) and the intensity of mixing are ensured. The drive 5 of the mixer 6 is switched on in the heat treatment of milk.

The prepared milk replacer is discharged from the tank through the pipe 21.

Flushing mode. The washing solution through the inlet pipe 2 is supplied under pressure to the washing manifold 15, and the spray nozzles 17 mounted in it provide intensive and uniform washing of the inner surface of the universal reservoir. From the flushing manifold 15, through the stuffing box 16, the solution is fed into the hollow shaft with flushing holes 14, leaving its openings to flush the working surfaces of helicoid 8. The drive 5 of the mixer 6 is turned on in the cream churn mode.

Removal of the spent solution is carried out through the pipe 21.

Then clean warm water is pumped through the rinsing system to remove residual detergent solution.

The control of the sanitary condition of the working surfaces of the tank, as well as the visual control of the technical condition of the internal mechanisms is carried out through the viewing window 10.

In any of the modes, the operation of the tank will be blocked in case of improperly closed cover 4 by means of limit switch 12.

The use of the inventive universal tank for processing and preparing liquid food products will allow to implement in such technological processes as: heat treatment of milk (pasteurization, cooling); ripening cream and receiving (production) butter; obtaining a substitute for whole milk based on secondary dairy products (skim milk, buttermilk) in one device.
