Description
Technical Field
The utility model relates to a food grinds the machine, in particular to grinder of adjustable powder size.
Background
The existing grinding device capable of adjusting the powder size mainly adopts two grinding modes to grind coffee beans into powder. One is to grind with a pair of identical flat grindstones with radial grooves, and the other is to use a tapered grindstone system, which is ground by a pair of grindstones of different calibers. In the two modes, one movable grinding stone in the grinding stone group is driven by an electric motor to rotate around a z-axis (vertical direction), and the other fixed grinding stone with a certain gap between the movable grinding stone and a movable sheet is fixed. The whole coffee beans usually enter from the center of the block and the coffee powder comes out from the gap between the sets of grindstones. Thus, the fixed grindstone is defined as the "front" grindstone (through which the coffee beans enter the grinding chamber), the movable grindstone is defined as the "rear" grindstone, and the fine adjustment of the gap between the two grindstones governs the thickness of the coffee powder. In order to vary the thickness of the coffee powder, the fixed front grindstone is mounted on a threaded outer housing marked with an up, down (along the Z axis) dial capable of increasing or decreasing the distance between the grindstone groups, the whole required travel distance of the fixed grindstone from the rotating grindstone (in the Z axis direction, coffee powder from finest to coarsest) being typically a few tenths of a millimeter. For reasons related to thread strength and cleaning requirements, in practice the mill manufacturer sets a stroke of a few centimeters (hundreds of times greater than necessary). Although the prior art structural design is relatively simple to manufacture and assemble for manufacturers of adjustable powder size milling devices. But the disadvantages are as follows:
1. complex structure, inconvenient use, higher cost and lower efficiency
During the grinding process, the dynamic grindstone transmits a strong torque force to the grindstone through the coffee powder and the granules. These torque forces must be reduced in order to prevent the fixed grindstone from performing unnecessary self-movements on the threaded screw, a functionally complex binary problem which has led for many years to the design of two mechanisms each with its own drawbacks:
a. a step fine adjustment structure, wherein a mechanical stop pin is used for fixing the fine adjustment knob during grinding. When the fineness of the ground coffee is set, a user firstly loosens the stop pin, and the fine adjustment knob is locked again after the grinding setting is changed.
The disadvantages are as follows: the abrasive setting is less selective, the stop pins must be in a specific dial-setting pocket or groove, and the user sometimes desires the abrasive setting to be between two fixed positions.
b. The continuous micro-step fine-tuning structure is characterized by that in order to block torque force of grinding stone, the fixed grinding stone supporting mechanism is formed from two portions, first portion is grinding stone supporting frame, it possesses a special ear to block torque, and second portion is screw portion for regulating position of grinding stone. The two parts work together to prevent the dynamic grindstone from transmitting torque to the threaded portion.
The disadvantages are as follows: the grinding machine has the disadvantages of complex structure, more parts, high precision requirement of the processing technology and low grinding efficiency.
2. Troublesome maintenance and waste of coffee
When coffee beans contain coffee oil, the coffee grinding chamber usually needs cleaning and wiping, and the cleaning operation is to open the fixed grindstone fixing frame, open the fine adjustment scale adjusting disc and separate the grindstone groups. After each cleaning step, re-conditioning is required to obtain the correct stone gap, a step which is time consuming, only performed by specially trained persons, and which wastes coffee.
3. Easily-polluted coffee
Another disadvantage of the prior art vernier system is that the screw vernier is located in the grinding chamber and the vernier movement should be very accurate without clearance between the two screw surfaces, since the screw mating surfaces need to be sufficiently tight (accuracy to facilitate grinding) and the screw working part generates a lot of metal dust which falls into the grinding chamber and mixes with the coffee powder. In addition, if not used for a long time, the zinc plating effects and oxides from the fine adjustment dial will stick in the grinding chamber.
