Description

Konjac peeling device and method

technical field

The present invention relates to the technical field of intelligent equipment, in particular to a konjac peeling device, and also includes a method for peeling konjac by using the konjac peeling device.

Background technique

With the vigorous development of the food processing industry, various values of fruits and vegetables such as chemical industry, medical treatment, and health care have been discovered. How to deeply process food to make use of its value has become more and more important to the society. Among them, peeling is an important part of fruit and vegetable processing. It is an important step for many follow-up deep processing to have higher requirements on the peeling rate of fruits and vegetables. At present, the common methods of peeling fruits and vegetables are as follows:

Manual peeling: Use special knives for peeling, planing and other operations for peeling. The peeling rate is high and the loss of pulp is less, but the overall efficiency is low, the output is limited, and some fruit and vegetable juices corrode the skin, so long-term work Can cause serious damage to the skin.

Mechanical peeling: Peeling by means of rotary cutting, hair roller scrubbing, friction, etc. It is mainly used for more conventional fruit and vegetable raw materials. It is difficult to peel fruits and vegetables with irregular surface shapes and more concave holes on the surface, resulting in more pulp loss and serious waste of raw materials.

Chemical peeling: Pectin has a fixed effect on the outer skin of fruits and vegetables. The principle of chemical peeling is to use chemical solution to decompose pectin to achieve the peeling effect. Caustic soda is commonly used, and certain experiments are required to determine the concentration and processing time of the chemical solution. The processed fruits and vegetables need to be rinsed with plenty of water until the surface has no alkali smell

Thermal peeling: Put the fruits and vegetables in steam, hot water and other media for short-term high-temperature treatment to make the pectin between the pulp and the peel lose its gelatinity, and then remove the waste peel adhered to the surface of the pulp through subsequent treatment. This method is suitable for fruits and vegetables with irregular surface shape or high maturity. This peeling method has high peeling efficiency, is not limited by the surface shape of fruits and vegetables, and has less pulp loss in the process of processing.

Enzymatic peeling: Use pectinase to decompose the pectin between the skins of fruits and vegetables to achieve the peeling effect. Because pectinase will be inactivated beyond a certain temperature and pH range, the working environment should be strictly controlled

Frozen peeling: The fruits and vegetables are treated at low temperature in the freezing equipment until the surface is slightly frozen, and then thawed, the pectin loses its gelatinity, and the peel and pulp are separated. This method of peeling is effective but the cost is high.

Konjac is a common rhizome fruit and vegetable with irregular surface shape. Its fruit is oblate and uneven on the surface. Because of its special growth environment and high value-added deep-processing products, research has found that the heteropolysaccharide konjac glucomannan extracted from konjac tubers Sugar (KGM) has pharmacological effects.

The pressure tank main body 10 The feed port of the pressure tank is movably connected with an inward-opening feeding end cover mechanism 12, and the outlet of the pressure tank main body 10 is movably connected with an outward-opening feeding end cover mechanism 13, and the inside of the pressure tank main body 10 is provided with a stirring mechanism 14. , mechanical peeling device 2 comprises frame 20, and frame 20 inside is provided with feeding chute, and is rotatably installed with the helical blade 21 that is used to transport material and some brush rollers 22 that are used for peeling in the feed chute, and the brush roller 22 is evenly arranged under the helical blade 21 in an arc shape.

The edible part of konjac fruit is oblate, and the surface is uneven. Traditional mechanical peeling is difficult to peel it thoroughly. The konjac peeling device of this embodiment includes a steam peeling device and a mechanical peeling device. The steam peeling device is Using thermal peeling, the loss of pulp is less during the process, effectively reducing the waste of materials in the peeling process, the peeling quality is high, and the skin on the concave part of the konjac surface can also be effectively removed. The peeling principle is physical peeling, no chemical The waste liquid is discharged without polluting the environment; the surface of the treated konjac will produce a 1-2 mm thick ripening circle, and the surface enzymes of the ripened pulp are inactivated, which hinders the precipitation of KGM in the ripening circle, which can prolong the konjac after peeling. The time when browning occurs; the material outlet of the steam peeling device is arranged right in front of the material inlet of the mechanical peeling device, and the processed konjac falls directly into the mechanical peeling device from the bottom of the steam peeling device without going through the screw elevator Conveying the material reduces the time the material stays in the equipment, improves the processing efficiency, and effectively avoids the browning of the konjac pulp.
