Preparation method of compound milk powder

Abstract

The invention discloses a preparation method of compound milk powder, which comprises the following steps: S1, filtering and sterilizing raw milk, adding different materials, sufficiently mixing the different materials with the raw milk, and storing the mixture in a temporary storage tank in a first bracket for later use; s2, feeding the raw milk in the temporary storage tank into a sterilizationtank, and heating the raw milk in the sterilization tank through a circulating energy-saving heating mechanism to eliminate harmful bacteria in the raw milk; The method is scientific and reasonable instructure and safe and convenient to use, the circulating energy-saving heating mechanism is arranged, steam is generated through evaporation of the two evaporation tanks together, and through cooperation of the hot air pipe, the compression pipe and the sterilization heating pipe, the steam is heated and then fed into the ascending air box at the bottom end of the sterilization tank; steam enters an ascending air box at the top end of the sterilization tank along an ascending air pipe, heats raw milk in the sterilization tank from bottom to top and then is exhausted into the liquefaction boxthrough a first exhaust pipe.

Description

technical field [0001] The invention relates to the technical field of milk powder production, in particular to a production method of compound milk powder. Background technique [0002] Milk powder is a powder made by removing water from animal milk. It is suitable for preservation. Milk powder is made of fresh milk or goat milk. It is frozen or heated to remove almost all the water in the milk. After drying, add an appropriate amount of vitamins. In the production process of milk powder, the raw milk must be condensed and sterilized through sterilization tanks and concentration tanks, so as to reduce harmful fungi and moisture in the raw milk and ensure the quality of subsequent milk powder production ; [0003] However, the existing sterilizers and concentration tanks only heat the raw milk from a single direction during the concentration and sterilization process, so that the heating degree of the raw milk at the top and the bottom of the inner wall of the sterilizing t...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method for making composite milk powder, which can effectively solve the problem of heating the raw milk only from a single direction in the process of concentration and sterilization proposed in the above-mentioned background technology, so that the raw milk at the top and bottom of the inner wall of the sterilizer can be separated. The degree of heating is inconsistent, resulting in uneven heating of raw milk. At the same time, when heating, the waste heat is not used reasonably to improve the heating effect and reduce energy consumption, so that part of the energy is wasted, which increases the cost and causes losses.
