Powder mill used for freeze-dried fruit powder

Abstract

The invention discloses a powder mill used for freeze-dried fruit powder. According to the technical scheme, the powder mill is characterized in that the powder mill comprises a powder collection device, a hoister, a dust collector, a stock bin, a sorting machine, a main machine assembly, a speed reducer, a jaw crusher and a feeder; the jaw crusher is connected with the hoister, and fruit and vegetable powder is conveyed to the stock bin through ascending and descending of the hoister; one end of the stock bin is connected with an air duct, the other end of the stock bin is connected with the feeder, and the fruit and vegetable powder enters the main machine assembly through the feeder; the sorting machine is arranged on the main machine assembly, a filter screen is arranged in the main machine assembly, and the fruit and vegetable powder passing through the filter screen enters the powder collection device for collection through a pipeline under the action of a blower; the dust collector is connected with one side of the main machine assembly; and the powder mill is made from stainless steel, and the interior of the powder mill is coated with a layer of food grade polyethylene plastic. The powder mill is reasonable in structural design and convenient to operate; and meanwhile, the inner layer of the powder mill is coated with the layer of food grade polyethylene plastic, so that the condition that metal elements in the powder mill seep out and pollute milled fruit and vegetable powder and consequently eating by people is influenced is avoided.

Description

technical field [0001] The invention relates to the field of food processing, and mainly relates to a mill for freeze-dried fruit powder. Background technique [0002] Mills are widely used in metallurgy, building materials, chemical industry, mining, food and other fields. According to the fineness of the ground material and the fineness of the discharged material, the mill can be divided into vertical pendulum mill, high-pressure suspension roller mill, high-pressure micro-powder mill, straight-through centrifugal mill, super-pressure trapezoidal mill There are six types of pulverizers: pulverizer, three-ring medium-speed pulverizer. The working principle of the mill is that after the material is crushed to the required particle size, the material is sent to the storage hopper by the elevator, and then the material is evenly and continuously sent into the main grinding chamber of the Raymond mill through the vibrating feeder. Under the action of centrifugal force, the gr...
