Preparation method of micro-capsule coated fat powder and hot spray drying device

Abstract

The invention provides a preparation method of micro-capsule coated fat powder and a hot spray drying device. The hot spray drying device comprises a supporting structure, afeeding structure, a pushing structure, and a preparation structure, wherein the feeding structure is arranged to be in an inclined downward shape, and the feeding structure is installed at the upper left end of the supporting structure in a clamped mode; the pushing structure is arranged to be of a horizontal structure, and the pushing structure is installed at the lower end position of the feeding structure; and the preparation structure is arranged to be in the shape of a hollow rectangular plate, and the rectangular plate is fixed to the right side end of the pushing structure. Materials are poured in through a funnel structure at the top of the feeding cylinder; the materials can directly fall into the bearing cylinder, and because the bearing cylinder is installed on the rotating shaft in a rotating state, the outer end of the pressing rod connected in the bearing cylinder in a sleeving mode can pressurize the materials to extrude the materials towards the right side of the bearing cylinder under the action of the inclined face of the right side of the fixed cylinder, and the materials are extruded out of the miniature through hole of the bearing cylinder; and extruded materials can be poked by five groups of blocking rods on the discharging plate, and the materials are cut into particles.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and more specifically relates to a method for preparing microcapsule-coated fat powder and a thermal spray drying device. Background technique [0002] Fat powder is a powder made from refined hydrogenated vegetable oil and a variety of food accessories after preparation, emulsification, sterilization, and spray drying. Fat powder is also called creamer and powdered oil. The product has good dispersibility and water solubility. , stability, used in various foods can increase nutritional value and calorific value, improve instant solubility and brewing properties, and improve taste. Fat powder is not a natural agricultural product, but an artificial preparation, so each product formula may have different Approximately, no two are exactly alike. [0003] In the patent application number: CN201510533620.6, the present invention discloses a microencapsulated fat powder feed additive and a pre...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a preparation method of microcapsule-coated fat powder and a thermal spray drying device to solve the problem that some materials are powdery when feeding the existing microcapsule-coated fat powder. The shape will cause inconvenience when feeding, and cause problems such as material jams at the end processing position of the feeding. The general granulation position will cause the problem of particle crushing under pressure when it is cooled, and will also cause problems. The problem of generating a lot of dust at the material position
