Preparation method of natural malus asiatica food colouring

Abstract

The invention discloses a preparation method of natural malus asiatica food colouring. A stirring space is formed in a working box; a storage space of which the upper end wall is communicated with thestirring space is formed in the lower end wall of the stirring space; a transmission space is formed in the right end wall of the stirring space; a linkage space is formed in the lower end wall of the storage space; a pushing space is formed in the right end wall of the linkage space; an extraction space of which the lower side of the left end wall is communicated with the pushing space is formedin the right end wall of the pushing space; and an atmospheric pressure tank of which the upper end wall is communicated with an outside space is formed on the upper end wall of the extraction space.The device is simple in structure and convenient and rapid to operate. According to the invention, in the working process, coloring matter in crops can be automatically collected, low-pressure operation can be implemented and use of energy is reduced, so that when energy is saved, emission of heat can also be reduced and the environment is protected.
