Description

A kind of preparation method of homogenized meal and grinding device for preparation thereof

technical field

The invention relates to the technical field of nutritional food processing, in particular to a preparation method of a homogenized meal and a grinding device for the preparation.

Background technique

Homogenate meal is used for sub-healthy people who are sickly, inappetence, chronic diseases, acute trauma, masticatory, digestive dysfunction, critically ill, cancer and surgical patients, poor or no masticatory function, oral and esophagus lesions or abnormal before and after surgery Nutritional supplementation for people who eat (with nasogastric tube feeding). At present, the raw materials used in the homogenized meal processing in the domestic market are basically based on the products that have undergone secondary processing. After mixing in a certain proportion, it provides heat energy supplement, such as: soybean powder, tomato powder, pumpkin powder, milk powder, non-dairy creamer, soybean protein powder, etc. The production of existing homogenized meal product has following shortcoming:

(1) Milk powder or soybean powder is added to the ingredients to increase protein. The milk powder contains lactose, which will cause diarrhea due to the inability of lactose intolerant people to digest normally, and may also cause abdominal pain, abdominal distension and other adverse symptoms;

(2) Non-dairy creamer is mainly used in the ingredients to control the fat content. Non-dairy creamer, also known as creamer, is a new type of product with refined vegetable oil or hydrogenated vegetable oil, casein, emulsifier, sodium aluminosilicate, etc. as the main raw materials. It is used to improve the taste of food, but it contains a lot of substances harmful to the human body. During the production process, the partial hydrogenation of vegetable oil is actually the process of turning the unsaturated fatty acids of vegetable oil into a saturated or semi-saturated state. Fatty acids, which can increase the low-density lipoprotein in the human blood, reduce the high-density lipoprotein, induce hardening of the arteries, and increase the risk of heart disease and cerebrovascular accidents;

(3) The vitamins contained in the raw materials such as tomato powder, pumpkin powder, carrot powder, etc. have been depleted by high-temperature dusting, so additional multivitamins should be added to the formula;

(4) When grinding raw materials with equipment such as colloid mill, the colloid mill is driven by the motor through the belt drive to drive the rotating teeth (or called the rotor) and the matching fixed teeth (or called the stator) for relative high-speed rotation. One rotates at high speed and the other is stationary. The material to be processed is pressurized by its own weight or external pressure (which can be generated by a pump) to generate downward spiral impact force, and is subjected to strong shearing force when passing through the gap between the fixed and rotating teeth , friction, high-frequency vibration, high-speed vortex and other physical effects, the material is effectively emulsified, dispersed, homogenized and pulverized to achieve the effect of ultra-fine pulverization and emulsification of the material.

The Chinese invention patent publication (announcement) No. CN107952521B discloses a colloid mill, which includes a feed hopper, a grinding body with a grinding space inside, a fixed grinding disc set fixed inside the grinding body, and a set for connecting with the fixed grinding disc set. The matching movable grinding disc group, the fixed grinding disc set includes a first fixed grinding disc and a coaxially arranged second fixed grinding disc, the moving grinding disc set includes a first moving grinding disc and a coaxially arranged second moving grinding disc, the first fixed grinding disc Both the moving grinding disc and the second moving grinding disc are connected with a drive shaft assembly for outputting rotational power, the drive shaft assembly is connected with a first pulley mechanism, and the first pulley mechanism is connected with a main motor for providing a power source. The material can be repeatedly ground and pulverized for multiple cycles, with multi-level and multi-level grinding each time.

Due to the centrifugal motion of the material during grinding, the flow rate is not constant, and the flow rate varies greatly for materials with different viscosities. For the same equipment, when dealing with viscous paint materials and thin milk fluids, the flow rate can vary by more than 10 times. Because the viscosity of the materials in the homogenized meal is relatively high after being cooked, especially the protein content in the formula is high, and because the protein has strong gel properties, the viscosity of the product obtained after the materials are mixed and heated according to the formula is high. Although the above colloid mill equipment can The final material grinding effect is improved by multiple grinding, but there are problems such as low flow rate, long grinding time, long production cycle and high cost in the preparation of homogenized meal by grinding.
