Purple Sweet Potato Freeze Dried Linear Vibrating Screen a screen is a machine used for particle size classification, impurity removal, and screening of freeze-dried materials in different forms, such as freeze-dried purple sweet potato granules, freeze-dried crushed purple sweet potato, and freeze-dried purple sweet potato powder. It is well-suited to the brittle, easily broken, and unevenly sized characteristics of freeze-dried purple sweet potato materials, avoiding problems such as material breakage, screen clogging, and contamination during the screening process. It can purify and remove impurities at a single particle size, and also achieve simultaneous grading of freeze-dried purple sweet potato materials of multiple specifications. It perfectly meets the batch continuous operation requirements of purple sweet potato freeze-drying production lines, can be customized with upstream and downstream equipment, supports 24-hour continuous operation, and can handle up to 20 tons per hour.
Purple Sweet Potato Freeze Dried Linear Vibrating Screen The screen boasts a compact and streamlined structure, comprised of six core components: a food-grade screen box, dual vibrating motors, multi-layered screen frames, vibration-damping springs, a support base, and an outlet. Its modular design facilitates easy disassembly and cleaning. The screen box, as the core carrier for material screening, uses food-grade materials for all parts in contact with the material. The dual vibrating motors are symmetrically mounted at the bottom of the equipment, ensuring uniform and stable vibration force. The screen frames feature a quick-release design for easy screen replacement and internal cleaning. Vibration-damping springs are installed between the base and the screen box to effectively buffer vibration impact. The inlet and outlet can be customized to fit the customer's production line.
ThePurple Sweet Potato Freeze Dried Linear Vibrating Screen utilizes the linear vibration force generated by the synchronous counter-rotating of dual vibrating motors to complete the screening operation. The two motor shafts are set at a specific tilt angle, generating a linear reciprocating vibration force in the same direction during operation. This force is transmitted to the screen box and screen, causing the freeze-dried purple sweet potato material to move forward in a uniform, linear, jumping motion on the screen surface. Material falls evenly into the top screen from the feed inlet. Under vibration, finer materials smaller than the corresponding screen aperture gradually pass through the holes and fall, while coarser materials move forward along the screen surface and are discharged from the corresponding outlet. The material passes through screens of different sizes layer by layer, ultimately completing the grading and sorting of different particle sizes.
Compared to ordinary screening equipment, the Purple Sweet Potato Freeze Dried Linear Vibrating Screen boasts multiple core advantages for food processing. Firstly, it offers food-grade safety; all parts in contact with materials are made of stainless steel, ensuring cleanliness and ease of cleaning, meeting food production hygiene standards. Secondly, it has an extremely low clogging rate, quickly separating materials of different sizes and improving product quality. Thirdly, it offers stable operation; dual-motor drive provides uniform vibration, resulting in low noise and a low failure rate, allowing for continuous 24-hour batch operation and significantly improving production efficiency. Furthermore, the equipment is highly flexible; screen specifications can be changed as needed, and the number of layers can be adjusted flexibly to adapt to different production requirements. It is also easy to operate, requiring no professional personnel and has low maintenance costs.

Our factory offers two models—a standard model and an air-cooled model—tailored to customer production needs and environments. Both models feature a food-grade design, adaptable to different production environments and production lines, meeting the screening, grading, and impurity removal requirements of purple sweet potato freeze-drying processing enterprises of varying sizes.
Standard Purple Sweet Potato Freeze Dried Linear Vibrating Screen: This is a basic and practical screening device, emphasizing cost-effectiveness. Suitable for small to medium-sized purple sweet potato freeze-drying processing enterprises and production lines with regular output, it requires no additional cooling system and is suitable for ambient temperature production environments. It provides stable and reliable screening results for purple sweet potato freeze-dried materials with normal moisture content and particle size. Installation and commissioning are simple, and maintenance is convenient. Suitable for production enterprises with moderate production scale and basic screening requirements.
Air-Cooled Purple Sweet Potato Freeze Dried Linear Vibrating Screen:This is an upgraded screening device equipped with a centrifugal fan cooling system. It can quickly cool the dried purple sweet potato freeze-dried material, facilitating screening and preparing it for subsequent packaging. It is especially suitable for large-scale freeze-dried food processing plants and high-output continuous production lines.
Our factory'sPurple Sweet Potato Freeze Dried Linear Vibrating Screen can be flexibly customized to meet actual production needs. It can accommodate up to 5 screen layers with 6 independent discharge ports, enabling simultaneous grading and sorting of 6 different particle sizes of freeze-dried purple sweet potatoes in a single feed, fully meeting the refined grading requirements of various specifications of freeze-dried purple sweet potato products. From the feed inlet to the bottom discharge port, the mesh size of each screen layer decreases sequentially. After being sieved layer by layer, the material is discharged from its corresponding discharge port. The layer distribution is reasonable, eliminating material mixing and cross-grading issues, resulting in clear grading. The screens are made of food-grade material with standard mesh size, allowing for easy replacement. The number of screen layers and mesh size can be flexibly adjusted according to product specifications to adapt to different production process requirements.
A freeze-dried fruit and vegetable food processing plant, specializing in the production of freeze-dried purple sweet potato granules and crumbled purple sweet potato meal replacement ingredients, previously suffered from low product qualification rates due to insufficient accuracy in its screening equipment, leading to a sharp decline in operational efficiency. Subsequently, a customized air-cooled purple sweet potato freeze-drying linear vibrating screen was installed. The parts of the equipment that come into contact with the material are made of 304 food-grade stainless steel, equipped with four layers of screens, using four specifications of 20 mesh, 40 mesh, 60 mesh, and 80 mesh. This effectively separates fine powder, large particles, and impurities from the freeze-dried purple sweet potato material, accurately grading freeze-dried products of different particle sizes, improving product uniformity by over 99%, fully meeting the company's needs for large-scale and standardized production.
The market price range for DaHan Vibration Machinery's Purple Sweet Potato Freeze Dried Linear Vibrating Screen is $800.00-$8,000.
