Description

High-efficient tealeaves rubbing crusher
Technical Field
The invention belongs to the technical field of machinery, and particularly relates to an efficient tea grinder.
Background
Tea is the most common beverage in people's life, with the development of social economy and the continuous improvement of people's living standard, the kind efficiency of tea is more and more, people's requirement to the diversification, health care, high-quality of tea is increasingly strong, no tea of good quality will have no place to stand in the market, tea production and preparation technology are a technology that must be mastered by the vast tea producers, it is the permanent subject of tea production research.
Traditional tea bag is adopted in the preparation of traditional tealeaves or the mode of direct bubble in time is used, but these two ways platform is too traditional, do not show the benefit of tealeaves completely, and most non-water-soluble nutrient substance who is rich in tealeaves also is difficult to be appeared absorbing by the bubble of water, the processing method of tealeaves is various now, smash tealeaves into powder when being special, powdered tealeaves can be applied to various places, for example cake, beverage etc. in addition, the human physical stamina directly digests tealeaves, absorb the interior nutrition of tealeaves. However, the traditional tea leaf crushing machine is poor in tea leaf crushing effect, and therefore, the efficient tea leaf crushing machine is designed by the technical personnel in the field of the invention to crush tea leaves.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides an efficient tea grinder, which aims to solve the following problems: how to efficiently crush tea leaves.
The purpose of the invention can be realized by the following technical scheme: a high-efficiency tea leaf pulverizer comprises a box body, wherein a closed cavity is arranged in the box body, an inlet is formed in the box body, and the inlet is closed through a box door; the bottom in the box body is provided with a collecting box; a guide plate which is gradually sunken from the periphery to the middle is fixedly arranged in the box body, a filter screen is fixedly arranged in the middle of the guide plate, and the guide plate and the filter screen divide the cavity into an upper cavity and a lower cavity; a discharging pipe is fixedly arranged on one side of the box body and is sealed through a first valve, the discharging pipe is positioned above the guide plate, and a blowing mechanism used for blowing tea powder on the guide plate to the filter screen and blowing uncrushed tea out of the discharging pipe is arranged in the box body; one side of the box body is also fixedly provided with a feeding box, and the feeding box is connected with the crushing barrel through a feeding pipe.
The working principle of the invention is as follows: place tealeaves in the feeding incasement, tealeaves enters into crushing barrel from the inlet pipe in, cuts up tealeaves through the shredder mechanism, then pulverizes tealeaves through grinding the mechanism, and on the deflector that tea powder entered into in the box after pulverizing, tea powder assembles along with the filter screen in the deflector middle to the deflector, then the tea powder that accords with the condition gets into and collects the incasement, and the tea powder that does not accord with the condition continues to stay on the filter screen. Then the blowing mechanism is started to blow out tea which does not meet the conditions from the discharging pipe. When tea leaves can not be screened out from the filter screen quickly, the blowing mechanism is started, and the filtering speed of the tea leaves can be improved. Through this grinding mechanism, can the efficient grind tealeaves and be the powder.
