A sugar strip introducing passage d is formed between the cutting ring 8 and the molding cavity position 71 of the mold main body 7.

The sugar strips g move in the guide track according to a circumferential track, and the direction of the circumferential track is perpendicular to the horizontal plane. When the sugar sticks g reach the highest point of the cutting ring 8 and are cut into sugar blocks, at the same time, the first opposite punching piece 91 and the second opposite punching piece 92 of the forming die which are perpendicular to the running direction of the sugar sticks g generate relative movement, and the sugar blocks are pushed into the forming cavity group of the forming die and are punched, so that the standard sugar grain shape is formed.

The coated powder-coated chewing gum has three layers of different structures, and the unique texture characteristics and chewing feeling of the coated powder-coated chewing gum bring brand new and excellent eating experience to consumers.

The aging temperature is generally controlled at 18-25deg.C, and the relative humidity is controlled at 40-50%, and the aging time is 12-24 hr.

Wherein the pre-coat slurry is typically a liquid; the precoat powder is typically a dry powder solid. The pre-coating paste is a liquid with a certain solid concentration, which is prepared by mixing edible colloid and sugar (or sugar alcohol) and a solvent (such as water) according to a certain proportion; the pre-coating powder is typically a dry powder mixture of edible gums and sugars (or sugar alcohols).

After the precoating is completed, the sugar granules need to be aged in an equilibrium manner to control the moisture content and hardness of the whole sugar granules, wherein the temperature of the equilibrium aging is 18-25 ℃, the relative humidity is 40-50%, and the time is 12-24 hours.

The hard coating process, commonly known as panning, is a process of repeatedly coating the surface of the sugar particles with a mixed syrup of edible colloid and sugar at a proper solid concentration. The hard coating process and the precoating process are all completed in a rotary coating pan. The mixed sugar solution is subjected to dispersion, permeation, friction, drying, crystallization and other actions on the surface of sugar particles and between the sugar particles, and the requirements of the weight, the appearance and the like of the sugar particles are met by controlling the rotating speed of a coating pot, the flow speed and the temperature and the humidity of drying air, the environmental temperature and the humidity and other conditions.
