Drying of Yam Slices

1、 Customer demand background

Southeast Asian food processing companies focus on exporting yam slices, but traditional drying methods are greatly affected by weather, have low efficiency, and difficult to meet hygiene standards. The customer urgently needs an energy-saving and environmentally friendly drying solution, requiring stable production capacity (processing 5 tons of fresh yam per day), uniform color of the finished product, and compliance with international food hygiene standards. At the same time, the local power plant has abundant exhaust heat resources, and customers hope to utilize this low-cost heat source to reduce operating costs and carbon emissions.

2、 Customized design of equipment

Innovative utilization of heat source: adopting corrosion-resistant heat exchangers to recover power plant exhaust gas (120-150 ℃), avoiding waste gas pollution materials through a pure hot air circulation system, increasing thermal efficiency by more than 40%, and reducing energy consumption costs by 60%.

Intelligent mesh belt drying system: ① Segmented temperature control: three-stage drying zone (80 ℃ → 65 ℃ → 50 ℃) gradually dehydrates, retaining the nutritional components of yam slices, with a golden color and no burnt spots. ② Multi layer mesh belt design: 304 stainless steel mesh surface, 12 meters x 2 meters five layer structure, variable frequency speed regulation matching different slice thicknesses, precise moisture content reduced to below 8% Environmental compliance: equipped with exhaust purification module, zero emissions during drying process, in compliance with EU CE and FDA food equipment certification.

Customer value highlights: After the equipment is put into operation, the customer’s production capacity increases by three times, and the product yield rate reaches 98%, becoming the first potato processing plant in the local area to pass carbon neutrality certification.

3、 The use of dried yam slices

① Food Processing and Export

Dried yam slices can be used as snacks (such as crisps), ready to eat foods, or cooking ingredients, making them easy to store and transport for a long time. Its moderate sweetness and rich nutrition make it suitable for processing into healthy snacks for export to markets such as Europe, America, and Southeast Asia.

② Production of medicinal and health products

Yam has the functions of tonifying spleen, lung and kidney, supplementing qi and yin. After drying, it can be used to make Chinese herbal pieces, capsules or granules, and is suitable for auxiliary treatment of spleen deficiency, diabetes, etc.

③ Food raw material supply

Dried yam slices can be further ground into powder and used to make noodles, pastries, or nutrient fortified foods, increasing the dietary fiber and trace element content of the product.

④ Extend shelf life and reduce losses

Fresh yam is prone to decay, and after drying, the moisture content drops to below 8%, which can significantly extend storage time, reduce transportation and storage costs, and is particularly suitable for large-scale agricultural processing enterprises.
