Problems solved by technology

However, the use of processing aids will bring the following problems: 1. As an anti-caking agent, it has no nutritional value at all; 2. Adding processing aids will bring risks, such as using silicon dioxide, which will bring excessive aluminum Because the precipitation method is commonly used in the production of silica at home and abroad, the by-products include polyaluminum chloride or aluminum sulfate, activated alumina and other components
Consuming aluminum-containing food for a long time can easily lead to health diseases and is not beneficial to the human body, so there is a safety risk in the use of silicon dioxide

Embodiment 1

[0031] Preparation of milk flakes:

[0032] The milk tablet base powder (with whole milk powder as the main raw material, adding glucose syrup, edible vegetable oil, white sugar, food flavors, nutrients, etc., after batching, sterilization, vacuum concentration and spray drying, the milk solid content is not low. 70% of the modulated milk powder used to produce milk tablets.) The vacuum feeder sucks the material into the dry granulator (manufacturer: Shijiazhuang Keyuan Machinery Equipment Co., Ltd., dry granulator model: GZL150-40L, below The model of the dry granulator used in each embodiment and comparative example is all identical with this embodiment), dry granulator process parameter: vertical feeding speed is 16rpm; Horizontal feeding speed is 50rpm; Press roller pressure is 7MPa; Press roller The rotation speed is 8rpm; the sieve structure of the granulation system is an orifice selection plate; the sieve diameter of the granulation system is 12 mesh, the upper sieve d...

Embodiment 2

[0035] Preparation of milk flakes:

[0036] The whole milk powder is sucked into the dry granulator through the vacuum feeder, and the process parameters of the dry granulator are as follows: the vertical feeding speed is 18rpm; the horizontal feeding speed is 80rpm; the pressing roller pressure is 10MPa; the pressing roller rotating speed is 10rpm; The system screen structure selects the sieve plate; the sieve diameter of the granulation system is 14 mesh, the sieve mesh diameter of the upper layer of the vibrating screen of the screening system is 5 mesh, and the sieve mesh diameter of the lower layer is 60 mesh. The prepared granules were pressed into shape by a tablet press, and the parameters of the tablet press were set at a pressure of 8 kN.

[0037] After dry granulation, the water content of whole milk powder particles is below 8%, and the particle size distribution is 10-100 mesh particles account for 66% of the total weight of the particle powder, of which 10-20 mes...

Embodiment 3

[0039] Preparation of milk flakes:

[0040] The skimmed milk powder is sucked into the dry granulator through the vacuum feeder. The process parameters of the dry granulator are: the vertical feeding speed is 23rpm; the horizontal feeding speed is 100rpm; the pressing roller pressure is 12MPa; the pressing roller rotating speed is 12rpm; The sieve structure is selected from the sieve plate; the sieve diameter of the granulation system is 14 mesh, the sieve mesh diameter of the upper layer of the vibrating screen of the screening system is 8 mesh, and the sieve mesh diameter of the lower layer is 100 mesh. The prepared granules were pressed into shape by a tablet press, and the parameters of the tablet press were set at a pressure of 8 kN.

[0041] After dry granulation, the water content of skim milk powder particles is below 8%, and the particle size distribution is 10-100 mesh particles account for 72% of the total weight of the particle powder, of which 10-20 mesh accounts ...

Abstract

The invention discloses application of dry granulating technology in the preparation of milk slices, and belongs to the field of milk slice preparation. In the invention, the application of the dry granulating technology in the preparation of the milk slices solves the problems existing in the traditional wet granulation and direct compression methods in the preparation of the milk slices, and improves sensory characteristics such as glossiness and integrity of the milk slices. The application of dry granulating technology provides a new reference and idea for the production of the milk slices, and the developed method is simple in technological operation and suitable for large-scale industrial production.

Description

technical field [0001] The present invention relates to the field of milk tablet preparation. More specifically, it relates to the application of a dry granulation process in the preparation of milk tablets. Background technique [0002] Milk tablets are dairy products with a milk solid content of ≥70% made from milk powder as the main raw material, added with fruit powder, flavors, etc., after mixing, tableting, and packaging. Because of its rich nutrition and convenient eating, it is very popular among consumers. [0003] The production process of milk tablets is divided into two types: granulation process and non-granulation process, that is, direct tablet compression. Among them, the granulation process is mainly wet granulation process, that is, the milk tablet raw material powder is sprayed with a wetting agent (usually water). ) into a soft material, which is then placed on a plate, baked and dried, granulated and then pressed into shape. The production method of t...
