The freeze dryer features an independent quick-freezing tank, allowing for the quick freezing of the next batch of products while processing in the freeze-drying tank. This reduces processing time per batch, thereby enhancing production efficiency.
Two sets vacuum maintaining systems are adopted, ensuring that production will not be affected by the failure of a single vacuum pump, thus preventing the scrapping of the entire batch due to pump malfunction.
The production equipment adopts one-step forming tray, ensuring hygiene without any dead corners and facilitating easy cleaning. This design complies with food safety and sanitation requirements. The trolley with anti-tray-slip rod are used to ensure stability during transportation and prevent slippage. The tray sizes range from 5m² to 200m², providing excellent versatility and uniformity.
The external multi-cold trap structure is adopted. This design eliminates the hygiene concerns associated with internal cold traps that are difficult to clean. Additionally, placing the cold trap above reduces the footprint and maximizes the utilization of the upper space in the workshop.
The refrigeration system adopts a parallel unit with multiple compressor heads, which can automatically adjust usage according to the load, greatly reducing production costs. The full-liquid supply uses the evaporator area effectively, maximizing heat exchange efficiency.
Our equipment is equipped with state-of-the-art instruments and meters from renowned international brands, ensuring high precision and exceptional quality. With the PLC PC control system, you can remotely monitor the production process and enjoy the added convenience of optional remote operation capabilities.
Heating plates utilize efficient radiation heating, ensuring uniform and even heat distribution across the materials. The internal circulation of hot water within the plates promotes optimal heat transfer efficiency. It also boasts excellent sealing properties, completely eliminating the risk of water leakage.
