Problems solved by technology

At present, the drying operation in the production of milk powder mainly adopts traditional spray drying and freeze drying methods. The traditional spray drying operation temperature is above 80°C, which will more or less destroy nutrients and consume high energy consumption. Although freeze drying is not Destroys nutrients, but consumes more energy

Embodiment 1

[0039] Embodiment 1: A kind of dry emulsion is prepared the method for milk powder

[0040] A method of drying emulsion to produce milk powder, using the "liquid material drying equipment" designed according to the patent "medicine and edible material processing equipment" to dry the emulsion to produce milk powder, according to the following steps:

[0041] S1. Equipment configuration: The configuration of the fan and pipeline makes the no-load wind speed in the positive pressure circulation pipe I be above 32 m / s when the fan works at the frequency of the power supply;

[0042] S2. Equipment start-up: turn on the power supply, start the fan and the blowback device of the bag filter, adjust the fan speed after the fan is started, so that the working current of the fan is 40-75% of the rated current; after the equipment is started, adjust the regulating valve of the bag filter The opening degree is 10-25%;

[0043] S3. Operation process:

[0044] S301. Feeding: Add the quali...

Abstract

The present invention relates to a milk powder preparation method by drying milk liquid. The milk powder preparation method by drying milk liquid is conducted by using a piece of "liquid material drying equipment" which is designed according to the claim 2 of the patent "medicinal and edible material processing equipment". The preparation method does not cause damage to the nutritional content of the milk powder due to low processing temperatures, and has the characteristics of low energy consumption due to low temperature inside the machine, heat dissipation of the device surface and low quantity of heat taken away by exhaust gas.

Description

technical field [0001] The invention relates to a method for preparing milk powder by drying emulsion, and belongs to the technical field of circulating fluidized bed and food processing. Background technique [0002] Milk powder is a powder made from fresh milk as raw material, which is dried by freezing or heating to remove moisture. Drying is the most important operation in milk powder production, which determines the quality and production cost of milk powder. At present, the drying operation in the production of milk powder mainly adopts traditional spray drying and freeze drying methods. The traditional spray drying operation temperature is above 80°C, which will more or less destroy nutrients and consume high energy consumption. Although freeze drying is not Nutrients will be destroyed, but the energy consumption is higher. Contents of the invention [0003] The purpose of the present invention is to invent a method for preparing milk powder by drying emulsion wit...
