A konjac chips drying machine is a useful piece of equipment for a variety of applications, including food production.

Despite the fact that this plant is a relatively new crop, its many uses go beyond its high nutritional value and use as an edible film.

Some of these benefits are outlined below. Konjac is a type of soluble polysaccharide fiber that is low in calories, yet packed with nutrients and antioxidants.

When preparing to dehydrate konjac, it is important to select the appropriate amount of material.

This product should be clean, preferably by a professional, as different varieties have different qualities and maturity.

Then, the product must be spread evenly on the drying tray, at least five centimeters thick, and allowed to dry for 68 hours.

The konjac will regain moisture when exposed to air, so it’s important to ensure that the product is vacuum packaged.

Service life

There is a long life span for a konjac chip drying machine if it is properly maintained and serviced.

The optimum drying temperature for this product lies between 52 and 63 degC.

A conical air-tight vessel can be used to prevent heat loss from the machine.

A ceramic cylinder is also a good choice. A conical cylinder can save space and is highly efficient in drying konjac.

The humidity level in the air is one of the determinants of the dried quality of the konjac flour.

Fresh konjac tubers have a high water content, making them susceptible to spoilage and mold.

Hence, they are often processed into dried chips and slices. During processing, konjac tends to brown.

SO2 is often added to the mixture to prevent browning and bleach the konjac gum.

The SO2 content is also specified in the specification of the konjac glucomannan.


The process of drying konjac chips involves milling the dry chips into powder. Then, they are cleaned using alcohol or vacuum evaporated.

The powder is then treated with superheated steam, if desired.

This process can produce a wide range of products, including chips. In the case of dried konjac, this process is ideal for producing healthy snacks.

Maintaining a konjac chips drying machine can also ensure a smoother product, and can be a hassle-free process.
