The method of cleaning food
(57) Abstract:Use: in food industry, in particular when cleaning food. The inventive products treat alternating electric field frequency of 8-10 Hz for a period of not more than 5 min, then treated in a microwave field with subsequent simultaneous effect of alternating electric field frequency of 8-10 Hz and microwave radiation in the range of 8-30 cm for a period of not more than 15 minutes The invention relates to a method of purification of food products, in particular sour cream and other colloidal systems and solutions.The known method of purification of food products, including processed products in the microwave field and the subsequent control.The disadvantage of this method of cleaning food is low quality.The technical result of this proposal is to improve the quality of treatment.This is achieved by the fact that before microwave treatment products treated by exposure to an alternating electric field of a frequency of 8-10 Hz for a period of not more than 5 min, and the processing in the microwave field is carried out in the range of 8-30 cm with subsequent simultaneous effect of alternating electric poletti food is illustrated by the following examples.Example 1. Take contaminated, in particular radionuclide, sour cream.Initially it is treated by exposure to an alternating electric field frequency of 8 Hz for 5 minutes followed by processing in the microwave-field radiation 8 cm, and then handle the simultaneous effect of alternating electric field frequency of 8 Hz and the influence of the microwave field in the range of 8 cm and within 10 minutesAfter processing is carried out quality control cream by known methods. An audit revealed a lack of radionuclides in the food product, i.e. cream usable in the food.Example 2. Take contaminated, in particular radionuclide, and vodka.Initially it is treated by exposure to an alternating electric field frequency of 10 Hz for 3 minutes followed by processing in the microwave field emission at 20 cm, and then handle the simultaneous effect of alternating electric field frequency of 10 Hz and the influence of the microwave field emission at 20 cm within 15 minutesAfter processing is carried out quality control of vodka by known methods. An audit revealed a lack of radionuclides in the beverage, i.e., vodka fit for upotrebi the ü.The invention can be used in the food industry for cleaning food. 1 Method of purification of food products, including processed products in the microwave field and the subsequent control, characterized in that the microwave treatment products treated by exposing them to alternating electric field frequency 8 10 Hz for a period of not more than 5 min, and the processing in the microwave field is carried out in the range of 8 to 30 cm, with subsequent simultaneous effect of alternating electric field frequency 8 10 Hz and microwave radiation in the range 8 to 30 cm for a period of not more than 15 minutes
FIELD: food industry; chemical industry; petrochemical industry; pharmaceutical industry; methods and devices of separation of liquid mediums.
SUBSTANCE: the invention presents the method and the device intended for utilization in food industry, chemical industry, petrochemical industry, pharmaceutical industry and ensures an increased efficiency of changing the physical-chemical structure of the liquid mediums. The liquid medium is fed in the form of the two counter-directed streams. The streams are sent in the parallel planes, swirled in the opposite directions, subjected at the mechanical loading to action of the hydraulic impacts and crumpling creating the liquid medium swirling turbulent streams rubbing from the center to the periphery. The liquid medium is fed by cycles, returning from periphery to the rotation center. After the separation process completion conduct processes of settling and filtering. The two counter-directed streams are subjected to swirling in the opposite directions at the identical speeds. In the device the operational tool is made in the form of disks, which are arranged coaxially with the capability of counter-rotation. On each disk there are the ring-shaped and radial grooves. The disks ring-shaped grooves and prominences are installed with a clearance into each other. The volume of the chamber between the disks and the body is connected by the channels to the inlet channels of the liquid medium feeding system. On walls of the chamber and on the external surface of the disks there are the ring-shaped and radial grooves. The disks ring-shaped prominences are mounted with a clearance in the ring-shaped grooves of the walls of the chamber. The shaft of the disks rotation is made horizontal.
EFFECT: the invention ensures an increased efficiency of changing the physical-chemical structure of the liquid mediums.

SUBSTANCE: this invention covers method of raw milk purification from toxic metals and includes adding of a sorbent agent, purification from sorbent agent, herewith raw milk intoxicated with metals in (1.1…4.0)±0.1 MAC concentration undergoes purification. Purification is performed until 0.5 MAC ratio is reached; contact with a sorbent agent is performed at 6°C, 5 minutes with mixing. Purification from a sorbent agent is performed by a centrifugal method at the separator-milk purifier for cold purification, herewith grapheme powder of 0.1:1000 ratio is used as a sorbent agent.
EFFECT: decrease of toxic metals concentration in raw milk to (95…97)±1% degree of purification.

SUBSTANCE: invention relates to a method for purification of defatted milk contaminated with copper, lead and zinc in a concentration from 0.13, 0.23 and 0.34 of MAC respectively. According to the method, one introduces into defatted milk with residual fat content equal to 0.10-0.20% a sorbent preliminarily hydrated with distilled water which sorbent may be represented by alumina oxide powder, broken rice or licorice roots extraction residue, the weight ratio of milk to the sorbents being 25:1. Then one proceeds with maintenance during 20-30 minutes at a temperature of 50-55°C and the sorbent removal by centrifugal method in a milk purifier separator.
EFFECT: invention allows to reduce concentration of copper, lead and zinc and bacterial population in milk and to produce a product of better quality.

SUBSTANCE: cheese whey is cleaned from casein dust and grease. Nanofiltration to 20÷30% content of dry substances with simultaneous 25÷50% demineralization, followed by crystallization, is carried out by means of the 3-fold 8-hour cyclic heat treatment of crystallizate. Said treatment consists in sequentially heating it with hot air at the temperature of 60°C for 4 h and cooling with cold air at the temperature of 0°C for 4 hours in each cycle. The crystallization is combined with evaporation till the dry substances concentration of ≥50%, with the subsequent separation into lactose and the demineralized delactosed cheese whey and drying of both components. Heating in each cycle is carried out to the temperature of 32°C, and cooling - to the temperature of ≤10°C.
