Description

A small kitchen waste treatment device and method

technical field

The invention belongs to the technical field of kitchen waste treatment, and in particular relates to a small kitchen waste treatment device and method.

Background technique

Food waste includes food processing waste and food residues, and is the main component of domestic waste. Due to the high content of moisture and organic matter, food waste is easily spoiled and deteriorated, producing various bacteria and pathogenic bacteria and emitting foul-smelling gases, polluting the environment and the atmosphere, and endangering human health. The "reduction and harmless" treatment of kitchen waste has attracted widespread attention from the whole society.

At present, domestic and foreign food waste treatment methods mainly include crushing and sewage discharge, landfill, composting treatment, and feed treatment. Although these processing methods have their own advantages, they also have great limitations. For example, the use of crushing and sewage disposal to treat food waste requires small equipment, low energy consumption, and simple operation, but the direct discharge of treated waste will increase the burden on the sewage treatment plant; sanitary landfill treatment of food waste not only wastes land resources, but also wastes The sewage and stench produced by fermentation will also cause serious secondary pollution to the surrounding environment. The composting treatment occupies a large area and has a long treatment cycle; the feed treatment equipment is bulky and consumes high energy. Therefore, the above-mentioned treatment methods are difficult to meet the requirements for the treatment of kitchen waste in specific environments such as ships and islands.

Contents of the invention

The technical problem to be solved by the present invention is to provide a small-scale food waste treatment device and method, which are suitable for the requirements of food waste treatment in special environments such as ships and islands.

The technical solution adopted by the present invention to solve the technical problem is to provide a small kitchen waste treatment device, including a support seat, a housing is arranged on the support base, and the right part of the housing protrudes from the support base; The shaft center of the left end of the body is connected with a speed regulating motor; the speed regulating motor is placed on the support base; the shaft center of the casing is provided with a screw auger; The upper part is provided with a feeding port; the upper part of the middle end of the housing is provided with a microwave generator; the upper part of the rear end of the housing is provided with an exhaust pipe, and the lower part is provided with a discharge port.

The shell is cylindrical.

There is an insulation layer on the outside of the shell.

The insulation layer is completely wrapped by glass wool.

A method of using a small kitchen waste treatment device, comprising the following steps:

(i) Pour the kitchen waste containing dirty oil and water into the cylindrical shell through the feed port, and then close the feed port;

(II) Stir and mix the kitchen waste in the housing under the action of the screw auger;

(III) Turn on the microwave generator to heat the kitchen waste;

(IV) The centrifugal fan is used to input air into the intake pipe for ventilation, and the waste gas generated during the drying process of food waste is drawn out by the centrifugal fan connected to the exhaust pipe and discharged into the subsequent waste gas treatment system;

(V) After the food waste stays in the casing for a specified time, the discharge port is opened, and the food waste is discharged through the discharge port under the action of the screw auger.

The wet basis water content of the food waste before treatment is 85%, the wet basis water content of the food waste after treatment is less than 8%, and the dried food waste is stored for more than 180 days without peculiar smell after packaging.

Beneficial effect

Compared with the prior art, the present invention has the following advantages:

(1) The inventive device uses microwave heating to dry and reduce the amount of food waste, which has high heating efficiency, fast drying speed and low equipment energy consumption;

(2) The device of the present invention is small in size, and is more suitable for installation and use of kitchens or restaurants on various types of ships and islands, and effectively solves the problem of disposing of ship kitchen waste.

(3) The device and method of the present invention can directly process the original kitchen waste containing dirty oily water, without sewage discharge during the treatment process, and the sewage treatment burden is small;

(4) The device and method of the present invention are easy to operate and easy to control.

Detailed ways

Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

Embodiment one:

As shown in Figure 1, the present invention provides a small kitchen waste treatment device, including a support base 9, a housing 4 is arranged on the support base 9, and the right part of the housing 4 protrudes from the support base 9; the housing The left end axis of the body 4 is connected with a speed-regulating motor 8; the speed-regulating motor 8 is placed on the support seat 9; the shaft center of the housing 4 is provided with a screw auger 2; The front end is provided with an air intake pipe 7, and the upper part of the front end is provided with a feed port 6; the upper middle end of the housing is provided with a microwave generator 5; the upper rear end of the housing is provided with an exhaust pipe 3, and the lower part is provided with an outlet pipe. The feed port 1; the shell 4 is cylindrical; the shell 4 has an insulating layer outside; the insulating layer is completely wrapped by glass wool.

During the drying process of food waste, the screw auger 2 in the device is driven by the speed-regulating motor 8 to rotate forward and reverse at a speed of 5-30 rpm and at intervals of 5 minutes to make the food waste evenly Heating and drying; when discharging, the screw auger 2 in the device is driven by the speed-regulating motor 8 to rotate forward at a speed of 5-30 rpm, and the dried kitchen waste is discharged into the discharge port 1 at a uniform speed.
