(54) METHOD FOR CRUSHING FROZEN RAW MATERIALS. ANIMAL ORIGIN

one

The invention relates to the meat industry.

There is a method of crushing m clear frozen blocks, involving the grinding of raw materials on a roll crusher 1.

There is also a known method of crushing imported animal-derived raw material, which involves grinding the raw material in several stages. 2.

The disadvantage of these methods is that the raw material after grinding is required to defrost.

 The purpose of the invention is to reduce the crushing process and at the same time to get the flesh at a given temperature.

The goal is achieved by the fact that according to the method of crushing frozen raw materials of animal origin, which involves grinding the raw material in several stages, in the first stage, grinding is carried out on a rotary crusher to particle sizes of 50-100 mm, in the second stage - on a hammer mill to particle sizes 5 10 mm, and at the third stage - on a roller crusher to the size of 100 microns or less, the latter stage being carried out with simultaneous heating of the crusher working bodies to 20-30 ° C.

Due to the susceptible heat and heat released due to an increase in the coefficient and force of friction between the working bodies and the product, at the third stage the frozen raw material is defrosted. In order to obtain the finished flesh, a full set of components is added to the raw materials, intended for the production of the desired finished product before the third grinding stage. Thus, at the third stage of grinding, simultaneous defrostation and intensive movement of the raw material with the components takes place.

Example 1. Blocks of frozen meat, with a size of, for example, 380x380x150 mm and a temperature of 18 ° C, are first crushed on a rotary crusher to sizes 80-90 mm, then on a hammer crusher to sizes 8-10 mm, then the raw material is fed to a roller crusher, the working bodies of which are heated to + 25 ° C, and the rotation speed of one shaft is 980 rpm, and the other speed is 400 rpm. As a result of heating the product from the shafts and due to friction, full defrosting of the raw material occurs with simultaneous grinding to sizes of 100 microns or less. For cooking the mince of the doctoral sausage, 25 kg of premium grade beef, 70 kg of bold pork per 100 kg of minced meat are required. Before the third stage of grinding, the raw material is added, kg: sodium chloride, 2.01 sodium nitrite 0.0075; granulated sugar 0,2,. nutmeg 0,03; skim milk powder 2; dry egg melange 0,822 per 100 kg of minced meat. In a roller crusher, simultaneous grinding, mixing with components and defrosting of the raw material occur. After this treatment, the stuffing is ready for cooking sausage. Example 2. Blocks of frozen meat, as in Example 1, are ground in a rotary and hammer crusher, and then the raw materials are fed to a roll crusher and working bodies. which is heated to -i-20 ° C, the relative speed of vrasha shafts is the same as in example 1. In the roller grinder, along with the raw materials, they are added to prepare milk sausage, kg: salt 2; sodium nitrite 0.0075; granulated sugar 0.12; black pepper 0.09; ground allspice 0.06; ground nutmeg 0.03. ICpOMe addition, 0.822 kg of dry egg melange is added to a roll crusher. 3 kg of skimmed milk powder per 100 kg of raw materials. To prepare dairy sausage, 35 kg of I grade beef, 60 kg of fat pork are required. 100 kg of raw materials. Example 3. Blocks of frozen meat, as in Examples I and 2, are ground in the same sequence. At the first stage, the raw material is crushed to the size of 50-60 mm, at the second stage - up to 5-7 mm, and at the third stage, the raw material with the components is fed into a roll crusher, the shafts of which are heated to + 30 ° C. As a result, the raw material is simultaneously crushed and defrosted. Example 4. Blocks of frozen meat, as in the previous examples, are ground first to. rotary crusher, then hammer, and when crushed on a roll crusher, the shafts are heated to -f 15 ° C. However, roll treatment with such a temperature does not completely defrost the raw material. Example 5. Blocks of frozen meat, as in the previous examples, are ground first on a rotary crusher, and then on a hammer crusher. When grinding on a roller crusher, the shafts are heated to -f40 ° C. In this case, the raw material is well crushed, defrosted and mixed. However, local heating of the raw material to such a temperature is undesirable from a technological point of view. The present invention allows a reduction in the crushing process, thereby producing a predetermined temperature. The invention of the method of crushing frozen raw materials of animal origin, mainly meat blocks, which involves crushing the raw material in several stages, characterized in that, in order to shorten the process and at the same time to obtain minced meat of a given temperature, particle sizes of 50-100 mm, in the second stage - on a hammer mill to particle sizes of 5-10 mm, and in the third stage - on a roller crusher to sizes of 100 microns or less, the latter stage being carried out simultaneously Heated working bodies of the crusher to 2030 ° С.
