Abstract

PURPOSE: Provided is a crusher for food wastes which allows plural cutter blades to cut and crush the food wastes effectively so that it is helpful in fermenting the crushed food wastes effectively afterward. CONSTITUTION: In equipments to crush the food wastes which consist of a separation vibrator, a screw conveyer and the crusher, the crusher for the food wastes is characterized by comprising the parts of: a rotation cutter which has plural cutter blades; an electromotive motor(14) which adjusts the rotation speed of the rotation cutter; an upper and a lower case which protect the crusher from outside; and an exit which is placed at lower edge of the crusher to release the crushed food wastes.

Description

Food Waste Mill {Food Waste Mill}

The present invention relates to an apparatus that can effectively achieve the crushing of materials such as food waste, organic materials and the like. Currently used shredders are not focused on shredding materials such as food waste or organic waste, so the shredding efficiency is not satisfactory in recycling food waste. In addition, since the cutter and the main shaft are integrated, it is inconvenient to separate or repair the blade, and it is expensive to replace or the blade is screw type, so the lumps may not be broken. There was a problem such as supply.

The present invention relates to an apparatus necessary for a process for easily crushing food waste prior to biogas generation and liquid fertilizer and solid fertilizer production by anaerobic digestion in recycling food waste. In developing a device for shredding. In addition, it is easy to repair in case of breakdown, the cost of replacing the blade and the power consumption are low, so it is in the development of a device suitable for the cause of resource recycling.

The apparatus is divided into three parts: a separate vibrator (FIGS. 1, 2), a screw conveyor (FIGS. 3, 4, 5) and a shredder (FIGS. 6, 7, 8). Food waste is gradually moved by the vibration of the vibrator on the upper plate (1) above the separation vibrator. At this time, the moving speed is determined according to the vibration period. The top plate is slightly inclined and the inclination angle is adjustable. Food waste from the top plate is sent to the food waste inlet (2) of the screw conveyor. Food waste falling from the inlet is stored in the space between the screw (3) and is mechanically pushed forward as the screw rotates. At this time, the feed rate is determined according to the rotational speed of the screw. Food waste that passes through the end of the screw goes through a full shredding process. The screw end is covered with a casing (4) to be cut off from the outside and the food waste falling from the screw falls on the shredding cutter blade (8) to be cut and crushed by the cutter. The cutter is protected by the upper casing 5 and the lower casing 6 as shown in FIG. 8 and its rotational speed is determined by the drive motor 14 to determine the grinding speed. The cutter has several blades attached to one plane, and these blade planes are arranged in a staggered arrangement. The maximum size of the food waste mass is limited by the gap between the blade plates and the gap between the blades. Simultaneous cutting action results in very efficient grinding. At this time, foreign matters such as metal, plastic, etc., which cannot be crushed, do not fall into the crushed material outlet 10 at the bottom of the cutter, but are bounced out by the action of the cutter and exited into the foreign material outlet. The cutter is individually bolted to the main shaft 11 and the crushed cutter can be easily replaced by opening the upper casing. One cutter plate consists of eight cutter blades, and the interval between each cutter plate is small enough to maintain a constant interval and constitute several consecutive pieces.

Through the present invention, the conventional crusher can efficiently cut and crush inefficient food waste, and can be crushed into a sufficiently small mass. The blades are configured independently so that the food waste is crushed more easily than the conventional crusher by the multiple crushing action by each blade. It is easy to replace when the blade breaks, and only broken cutter can be replaced. The shredding size is very small since it consists of several cutter plates and the blades are staggered.
