With its efficient processing capacity, stable operating performance and wide range of applications, the double-axis food waste crusher has become an ideal choice in the field of food waste treatment, providing strong technical support for solving the problem of food waste.

The double-shaft food waste grinder is a device specially used for processing food waste. Its working principle is based on a unique mechanical structure and mechanical principle. Through the synergy of two rotating knife shafts, food waste is broken into fine particles for subsequent processing.

Core structure foundation

The core component of the double-shaft food waste grinder is two knife shafts that are parallel to each other and rotate synchronously in the opposite direction. There are multiple blades evenly distributed on each knife shaft. These blades are usually made of high-strength, high-wear-resistant alloy steel, with sharp edges and sturdy blades, which can withstand the impact and wear of food waste. The knife shaft is installed on a sturdy frame and connected to the motor through a transmission device to ensure that the knife shaft can rotate stably and efficiently.

Detailed explanation of the crushing process

When food waste is put into the feed port of the grinder, it will first enter the crushing chamber between the two knife shafts. At this time, the two knife shafts begin to rotate synchronously in the opposite direction, driving the blades to move relative to each other. The relative movement between the blades generates strong shearing force, tearing force and extrusion force, just like two crossed scissors, cutting and tearing the food waste.

For softer food waste, such as leftovers, fruit and vegetable peels, etc., the blades can easily cut them into small pieces. For some harder food waste, such as bones, nut shells, etc., the blades crush them through strong extrusion force. During the crushing process, the food waste will be constantly turned and squeezed between the blades to ensure that each part can be fully crushed.

Discharge and particle size control

After crushing, the food waste will become fine particles, which will be discharged from the discharge port of the grinder. In order to control the discharge particle size, the grinder is usually designed with adjustable blade spacing. By adjusting the spacing between the blades, the degree of cutting and squeezing of the food waste by the blades can be changed, thereby controlling the size of the crushed particles. Generally speaking, the smaller the blade spacing, the finer the crushed particles; the larger the blade spacing, the coarser the crushed particles.

The double-shaft food waste grinder uses two synchronously counter-rotating knife shafts and the blades on them, and uses multiple mechanical actions such as shearing, tearing and squeezing to achieve efficient crushing of food waste, which provides convenience for the subsequent treatment and resource utilization of food waste.
