Innovative Design and Wide Applicability of DWT Series Vegetable Dehydration and Drying Machine
Date: 2025-12-31Read: 14
In the field of food processing, vegetable dehydration and drying are key steps to extend shelf life and maintain nutrition. The DWT series vegetable dehydration dryer launched by Changzhou Xiangteng Drying Equipment Co., Ltd. is widely used in multiple industries due to its innovative design and wide applicability. This article will focus on the innovative design features of the device and the diversity of processed materials, demonstrating its superior performance through specific cases.
1、 Innovative design features: engineering breakthroughs that enhance efficiency and quality
1. Multi layer circulating conveyor belt and automatic material mixing device
The DWT series dryer adopts a multi-layer circulating conveyor belt design, combined with an automatic feeding device, to achieve uniform distribution and continuous drying of vegetables. For example, when processing garlic slices, the multi-layer structure of the conveyor belt ensures that the garlic slices are evenly heated during the drying process, avoiding local overheating and coking. The automatic material mixing device precisely controls the material flow rate, reduces manual intervention, and improves production efficiency. This design significantly shortens the drying time while maintaining the color and flavor of garlic slices, meeting the high standards of food processing requirements.
2. Optimization of box structure and hot air circulation system
The equipment adopts a box structure, equipped with efficient heat exchangers and dehumidification fans, forming a scientific hot air circulation system. Taking pumpkin drying as an example, cold air is heated by a heat exchanger and flows through the pumpkin chunks on the bed surface for uniform heat and mass exchange. The hot air flow inside each unit repeatedly flows under the action of the circulating fan, discharging low-temperature and high humidity air to ensure a smooth and efficient drying process. This design not only improves energy efficiency, but also reduces operating environment humidity and minimizes material waste.
3. Adjustable parameters and automation control
The DWT series dryer supports independent adjustment of drying area, air pressure, air volume, temperature, and mesh belt speed to adapt to different vegetable characteristics. For example, in carrot drying, by adjusting the air volume and temperature, the rate of water evaporation can be precisely controlled to avoid nutrient loss caused by excessive drying. The automation control system further simplifies operations, reduces human errors, and improves product consistency, making it particularly suitable for large-scale continuous production scenarios.
2、 Diversity in handling materials: covering the drying needs of multiple types of vegetables
1. Root vegetables: garlic slices, carrots, and white radishes
Garlic slices: The DWT series dryer uses a pulse airflow design to quickly evaporate the surface moisture of garlic slices, maintaining their spicy flavor and nutritional value. The multi-layer conveyor belt ensures that the garlic slices are evenly heated, avoiding clumping. After drying, the product has a golden color and is suitable for export markets.
Carrots and white radishes: When processing sliced or block shaped radishes, a hot air circulation system is used to achieve efficient dehydration. Dried radish slices have low moisture content, are easy to store for a long time, and retain their natural sweetness. They are widely used in food processing and catering industries.
2. Leafy vegetables and fruit vegetables: spinach, pumpkin, and apple
Spinach: In response to the fragile nature of leafy vegetables, the DWT series adopts a low-temperature drying mode to avoid high temperature damage to chlorophyll. The dried spinach slices have a bright green color and good rehydration properties, making them suitable for making instant vegetable powder or seasonings.
Pumpkin and Apple: When processing large pumpkin chunks, the device accelerates water evaporation through pulsed airflow, shortening the drying cycle. Apple slices are designed with adjustable airflow to maintain a soft and chewy texture of the flesh. Dried products are widely used in baking and snack processing.
3. Featured vegetables: konjac, yam, and bamboo shoots
Konjac: Konjac flakes have high viscosity and are prone to sticking to conveyor belts. The DWT series is equipped with anti stick coating and automatic scraper brush to ensure even distribution of materials. After drying, the konjac flakes have high transparency and are suitable for making konjac flour or instant products.
Yam and bamboo shoots: During the drying of yam slices, the equipment controls the temperature in sections (high temperature evaporates water, low temperature maintains texture) to avoid coking. Bamboo shoot slices utilize pulsed airflow to enhance heat transfer efficiency, resulting in crispy and tender products that retain their natural fragrance after drying.
Conclusion
Changzhou Xiangteng Drying DWT series vegetable dehydration dryer has become an ideal choice for the food processing industry through innovative design (such as multi-layer conveyor belts, hot air circulation, and adjustable parameters) and a wide variety of processed materials (covering roots, leafy vegetables, fruits, and specialty vegetables). Its efficient and energy-saving characteristics not only improve production efficiency, but also ensure the nutrition and flavor of vegetables, creating more value for enterprises and consumers.
