How is matcha powder prepared
Matcha powder is a popular name for matcha, which is a steamed green tea that is ground into a fine powder using a natural stone mill. It is currently a nutritious tea product. Due to its natural bright green colorIts ultrafine powder state is convenient for large-scale use in more fields; The essence of healthy nutrition has been recognized by people for thousands of years.
Matcha powder is a ultra-fine powder made from sun shading tea as raw material, which is then ground into powder by a matcha grinder. Only matcha powder pursues green color, and the greener the color, the higher its value, and correspondingly, the more difficult it is to makeThe larger the tea, the more stringent the requirements for tea varieties, planting methods, planting areas, processing techniques, and processing equipment.

The traditional process for preparing matcha involves withering the tea leaves, followed by drying, and then rolling them into a powder using mechanical equipment. Although these old processes can save significant costs on production equipment, they do waste a lot of raw materials. In addition, there is a fatal point that the powder produced by rolling is uneven and the fineness is not ideal. For the preparation of such substances, Taicang Xide Machinery and Equipment Co., Ltd. recommends that the wet grinding method be used to grind and disperse the materials first, and then spray drying, so that the production efficiency and quality can be greatly improved.

Among the numerous devices in Xide, the editor recommends using SID colloid mill for the preparation of such substances. Why is this? Let me explain it to you first:
Introduction to colloid mill
The basic working principle of colloid mill is shearing, grinding and high-speed stirring. Grinding relies on the relative motion of two tooth shaped surfaces, one rotating at high speed and the other stationary, causing the material passing between the tooth surfaces to experience shear and friction forces, while also effectively dispersing, floating, pulverizing, and homogenizing the material under complex forces such as high-frequency vibration and high-speed vortices.
Compared to the pressure homogenizer, the colloid mill is first a centrifugal equipment, which has the advantages of simple structure, convenient equipment maintenance, and is suitable for materials with higher viscosity and larger particles. Its main drawback is also determined by its structure. Firstly, due to centrifugal motion, the flow rate is not constant, corresponding to significant changes in flow rate for materials of the same viscosity. For example, the same equipment can have a flow rate difference of more than 10 times when handling viscous paint materials and thin dairy fluids; Secondly, due to the high-speed friction between the stator and the material, a large amount of heat is easily generated, causing the processed material to denature; Thirdly, the surface is prone to wear, and after wear, the refinement effect will significantly decrease.

The SID improved colloid mill combines various mechanical properties such as homogenizers, ball mills, three roll machines, shearing machines, and mixers, and has superior effects in ultrafine grinding, dispersion emulsification, homogenization, and mixing. After processing, the material has a particle size of 2-50 microns and a homogeneity of over 90%, making it an ideal equipment for ultrafine particle processing. This machine is suitable for ultrafine grinding of wet materials in the pharmaceutical, food, chemical, and other industries. It can crush, emulsify, homogenize, and mix various semi wet and emulsion substances, and its main technical indicators have reached the advanced level of similar foreign products.

The SID high shear colloid mill adopts a three-stage staggered grinding head fixed rotor, with a clearance between the grinding head fixed rotor of 0.2-0.7mm. The clearance can be adjusted by adjusting the adjustment handle of the high-speed homogenizer itself. Under the same speed, the smaller the clearance, the better the high-speed grinding and dispersion effect. The high-speed colloid mill, as the name suggests, has an extraordinary rotational speed. SID engineers have changed the transmission ratio of the belt pulley, allowing the equipment to reach a rotational speed of up to 9000rpm instead of the original 3000rpm motor. Practice has proven that with constant clearance between the grinding head and rotor, the higher the rotational speed, the better the grinding and dispersion effect of the high-speed homogenizer. If customers want to achieve better results with their materials, we offer Danvers frequency converters for customers to choose from. The high-speed homogenizer can reach a speed of 14000rpm after frequency conversion guo 4-5 times the speed of the internal equipment, it can be said to be a ji speed.

The high shear colloid mill consists of an electric motor, a connecting body, a grinding head, etc. The grinding disc is made of forged stainless steel and has three or more grooves on the surface, divided into three stages. The number, direction, and width of the groove teeth in each level are different. The more one level extends outward, the higher the precision of the grinding disc, the smaller the tooth pitch, the longer the linear velocity, the finer the material is ground, the more teeth there are, the larger the shear surface, the longer the linear velocity, the faster the fluid velocity, and the better the refinement effect. Mechanical seals can be divided into three types: hard internal mechanical seals, external double-sided hard mechanical seals, and metal corrugated hard mechanical seals. The grinding disc teeth can undergo special nitriding treatment as needed to enhance their hardness and provide better wear and corrosion resistance. Rotary and fixed grinding can be manually adjusted according to material viscosity, yield, and particle fineness. Their functions include high shear rate, long line speed, no dead corners, large processing capacity, and good homogenization and refinement effect.

Grinding and dispersing machine is a high-tech product composed of colloid grinding and dispersing machines.

The level consists of three-level sawtooth protrusions and grooves with increasing precision. The stator can be infinitely adjusted to the desired distance between the rotors. Under enhanced fluid turbulence. The groove can change direction at each level.
The second stage is composed of a stator. The design of the dispersing head also effectively meets the needs of substances with different viscosities and particle sizes. The difference in the design of the stator and rotor (emulsifying head) between online and batch machines is mainly due to the requirements for conveying performance. It is particularly important to note that the difference between coarse precision, medium precision, fine precision, and other types of working heads is not only the arrangement of specified rotor teeth, but also an important difference in the geometric characteristics of different working heads. The width of the slot and other geometric features can alter the different functions of the stator and rotor working heads.
