Embodiment 1

[0019] Such as figure 1 , 2 As shown, a method and equipment for removing impurities from matcha, including a screening machine 1, a metal detector 2 and an iron remover 3, or a metal detector with the function of removing iron, and a material bucket 4 is placed at the material outlet under the metal detector, Special cloth cover 5 Unicom material outlet and material bucket import. The screening machine is an ultrasonic vibrating screen. The material is matcha powder.

[0020] This matcha impurity removal method is as follows: first, turn on the power switch of the metal detector, verify the metal detector before use, open the material channel above the metal detector, turn on the metal detector to make it in operation, and verify The test piece used is verified by a metal detector to ensure that the equipment is normal and then the upper material port is closed; secondly, a sterilized clean material bucket is placed at the material outlet below the metal detector, and a sp...

Embodiment 2

[0022] Such as image 3 As shown, in the above-mentioned matcha impurity removal equipment, the upper port of the iron remover is in communication with the discharge port of the metal detector. The iron remover includes a vertical material flow pipe 6, and a conical shunt cap 7 is arranged in the material flow pipe. The top end of the shunt cap Upward, there is a gap for the material to pass between the split cap and the wall of the material flow pipe. The split cap is a magnet, and the outer wall of the material flow pipe below the split cap is provided with a magnet 8 . When working, the material enters the material circulation pipe and is guided by the diversion cap to disperse around, and flows down from the gap between the diversion cap and the wall of the material circulation pipe, and the iron filings in the material are adsorbed to the material circulation pipe on the diversion cap and the magnet. on the inner wall.

Embodiment 3

[0024] Such as Figure 4 , 5 As shown, in a kind of matcha impurity removal equipment, the screening machine includes a cylindrical screen frame 9 and a screen cloth 10 arranged at the lower port of the screen frame. The shaft 11 that rotates relative to the screen is connected with the iron rod 12 that diverges outwards with the shaft as the axis. The iron rod and the shaft are both soft magnets. Iron 13, the shaft is connected with the motor shaft, the motor controls the rotation of the shaft, the motor 17 is controlled by the lifting device 14, and the screen frame is provided with a groove 15 extending radially outward along the screen frame. There is a downward storage space for iron filings, and a buffer pad 16 is provided on the inner wall of the groove corresponding to the opening of the groove.

[0025] The above-mentioned method for removing impurities from matcha is: put the material on the screen, rotate the motor shaft so that the iron rod rotates on the screen ...

Abstract

The invention provides a matcha decontaminating method and equipment, relates to a matcha processing technology, and solves the matcha powder decontaminating problem in the prior art. In the matcha decontaminating method and equipment, firstly, a power supply switch of a metal detector is turned on; the metal detector is verified before use; a material channel above the metal detector is opened; the metal detector is started to locate in an operation state; a testing piece for verification is verified through the metal detector; after normal equipment is guaranteed, an upper material port is closed; secondly, a disinfected material cleaning barrel is put in a material outlet below the metal detector, and a special cloth sleeve is used for sleeving the material outlet to prevent leakage oftea; then, a material barrel with matcha is put on an elevator; a vibration screen starting switch is turned on; and the matcha is fed in the material inlet for screening by using a stainless steel spoon. A screening machine is matched with the metal detector for use to remove impurities in the matcha, so that the quality of the matcha is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of matcha processing, and relates to a method and equipment for removing impurities from matcha. Background technique [0002] Matcha originated in the Sui and Tang Dynasties of China. The young leaves of spring tea are steamed and then made into cake tea (tuancha) for preservation. It is baked and dried again on the fire before eating, and ground into powder with a natural stone mill. Nowadays, machines are usually used for large-scale processing or production, but the use of machines in the production process is easy to cause metal, especially iron impurities, to enter and pollute, so it is necessary to remove impurities from matcha powder. Contents of the invention [0003] The object of the present invention is to solve the above problems in the existing technology, and propose a method and equipment for removing impurities from matcha. The method and equipment for removing impurities from matcha are ...
