Problems solved by technology

[0014] The purpose of the present invention is to provide a method of direct mixing to make the compounding and mixing of superfine powder uniform. The direct mixing method is used to solve the problem of uneven mixing caused by compounding and agglomeration of superfine powder. The present invention does not require various complicated preparations. Granulation process, you only need to select the set preparation auxiliary materials (granules with a particle size of 40-60 mesh), the matching ratio of the set range, and the set mixing pre-treatment process to ensure that the direct mixing method will be used to mix super Process purpose of mixing fine powder with other raw materials evenly

Embodiment example 1

[0030] Pre-experiment: confirm the particle size of sorbitol and black bean purslane baking powder, take ≤99% as the test standard, it is confirmed that the particle size of sorbitol is 93% and over 40 mesh, and the black bean purslane baking powder is 99% pass through 80 mesh, so as to determine the mesh selection of raw material sieving. Among them, sorbitol is pure white, and the color of black bean purslane baking powder is gray-green.

[0031] Experiment 1: The black bean purslane baking powder and sorbitol were sieved respectively according to the mass ratio of 1:2 (the former was 80 meshes, the latter was 40 meshes), then put into the mixer at 14rpm / min, and mixed for 30min and sampled Check the appearance.

[0032] Experiment 2: The black bean purslane baking powder and sorbitol were premixed at a mass ratio of 1:1 and then sieved (40 mesh), then put into a mixer at 14 rpm / min, and mixed for 30 min to take samples to check the appearance.

[0033] Experiment 3: The b...

[0040] Pre-experiment: confirm the particle size of maltitol and probiotics baking powder, take ≤99% as the test standard, it is confirmed that the particle size of maltitol is 98% over 50 meshes, the appearance is white granular, and the probiotics baking powder is 99% is over 100 mesh, and the appearance is gray-brown ultrafine powder.

[0041] Experiment 1: The probiotic baking powder and maltitol were sieved respectively according to the mass ratio of 1:2 (the former 100 mesh, the latter 50 mesh), and then put into the mixer at 14 rpm / min, and mixed for 30 minutes to check the appearance.

[0042] Experiment 2: The probiotic baking powder and maltitol were premixed according to the mass ratio of 1:1 and then sieved (40 mesh), then put into the mixer at 14 rpm / min, and mixed for 30 min to take samples to check the appearance.

[0043] Experiment 3: Premix the probiotic baking powder and maltitol according to the mass ratio of 1:2 and then sieve (40 mesh), then put it into the...

[0051] Pre-experiment: Confirm the particle size of maltitol and red yeast rice flour, and take ≤99% as the test standard. It is confirmed that the particle size of maltitol is 98% and over 40 meshes, the appearance is white granular, and the red yeast rice flour is 93%. Over 60 meshes, the appearance is purple-red ultrafine powder.

[0052] Experiment 1: The red yeast rice flour and maltitol were sieved respectively according to the mass ratio of 1:3 (the former was 60 mesh, the latter was 40 mesh), and then put into the mixer at 14 rpm / min, and mixed for 30 minutes to check the appearance.

[0053] Experiment 2: The red yeast rice flour and maltitol were premixed according to the mass ratio of 1:1 and then sieved (40 mesh), then put into the mixer at 14 rpm / min, and mixed for 30 min to take samples to check the appearance.

[0054] Experiment 3: The red yeast rice flour and maltitol were premixed according to the mass ratio of 1:2 and then sieved (40 mesh), then put into the...

Abstract

The invention discloses a method for uniformly compounding and mixing ultrafine powder in a direct mixing manner, and belongs to the technical field of mixing preparations such as tablets, capsules and solid beverages, and the mass of plant food ultrafine powder is smaller than that of food preparation auxiliary materials. The food ultrafine powder and the preparation auxiliary materials are premixed, sieved and fully mixed. The mass ratio of the plant food ultrafine powder to the food preparation auxiliary materials is (1: 2)-(1: 3). And the plant food ultrafine powder is 60-100 meshes. The size of the food preparation auxiliary materials is 40-60 meshes. The food ultrafine powder and the preparation auxiliary materials are premixed and then pass through a 30-60-mesh sieve. The technical purpose of uniformly mixing the ultrafine powder with other raw materials in a direct mixing manner can be ensured only by selecting food preparation auxiliary materials and plant food ultrafine powder with specific technical specifications, matching mass ratio in a specific range and a set mixing pretreatment process.

Description

technical field [0001] The invention belongs to the technical field of mixing preparations such as tablets, capsules and solid beverages, and can be applied to probiotic oral microbubble tableting candies, red yeast rice, bamboo leaf flavonoids, and black bean purslane tableting candies. The direct mixing method makes the superfine powder compound and mixed evenly, which solves the problem of uneven mixing caused by the agglomeration of the superfine powder compounded by the direct mixing method. Background technique [0002] Terminology Explanation: [0003] Gradient mixing: It is generally used for mixing materials with large mass fractions and materials with small mass fractions. In order to ensure that materials with small mass fractions can be fully dispersed in materials with large mass fractions, a large mass fraction of the same weight as the materials with small mass fractions is usually taken. The materials are premixed first to form a premix, and then a large mas...
