High-temperature calcining apparatus for preparing food-grade tricalcium phosphate

Abstract

The invention discloses a high-temperature calcining apparatus for preparing food-grade tricalcium phosphate. The high-temperature calcining apparatus comprises a calcining work chamber, calcining pipes and a shelving device. According to the invention, one ends of the calcining pipes are fixed to the inner wall of the calcining work chamber, the other ends of the calcining pipes are inclined towards movable plates, and altogether four calcining pipes are symmetrically arranged relative to the movable plates, so the calcining pipes in the structure of the apparatus can realize more uniform calcining of the movable plates; two shelving frames are arranged along the longitudinal direction of the calcining work chamber, the calcining work chamber is provided with sliding chutes correspondingto fixed sliding blocks, and the fixed sliding blocks are slidably connected with the sliding chutes, so the structure is simple and clear, and has high practicability; and the movable plates and movable rods are movably connected with the shelving frames, the movable rods are fixed to the lower end faces of the movable plates, and fixed protruding blocks are elastically connected with conveying belts through torsional springs and are movably connected with the movable rods, so the movable plates in the novel structure can be jacked up rhythmically, and better calcining effect is obtained.

Description

technical field [0001] The invention relates to the technical field related to the preparation of tricalcium phosphate, in particular to high-temperature calcining equipment for the preparation of food-grade tricalcium phosphate. Background technique [0002] Tricalcium phosphate, also known as calcium phosphate, is white crystal or amorphous powder. There are many crystal transformations, mainly divided into low-temperature β-phase and high-temperature α-phase, after which the phase transition temperature is 1120°C-1170°C, and the melting point is 1670°C; soluble in acid, insoluble in water and ethanol; tricalcium phosphate is a safe It is mainly added in foods to strengthen calcium intake, and can also be used to prevent or treat symptoms of calcium deficiency. At the same time, tricalcium phosphate can also be used as anti-caking agent, PH value regulator, buffer agent, etc. in food. Such as flour anti-caking agent (dispersant), milk powder, candy, pudding, condiment, me...

AI Technical Summary

Problems solved by technology

Such as flour anti-caking agent (dispersant), milk powder, candy, pudding, condiment, meat additive, animal oil refining aid, yeast food, etc. The current preparation method of food-grade tricalcium phosphate is complex and cumbersome, and the manufacturing equipment is expensive , so we propose a food-grade tricalcium phosphate preparation high-temperature calcination equipment to solve the above problems
