Vacuum Lyophilizer for Food from 30 to 40 kg YR07072

Lyophilization removes water from the frozen product through sublimation: ice goes directly to vapor under vacuum. The equipment offers a cold trap temperature of −55 °C and a final vacuum of less than 2 Pa. Its PLC system allows for the configuration of parameters such as temperature, time, and vacuum; it also includes preset processes, fault diagnostics, and protections to help control the cycle. The transparent door allows observation of the process, and the automated operation starts with a button.

The actual capacity of each batch depends on the food, its water content, the thickness of the pieces, and how they are distributed on the trays. The data also indicates a water collection of 40 kg/24 h; this figure describes the moisture collection capacity and should not be confused with the processing capacity of 40–42 kg per batch.

Market Price

The price of a commercial food lyophilizer depends on capacity, tray area, cold trap temperature, controls, origin, and included services. As a reference, equipment is available for capacities close to 30–40 kg per batch starting from approximately US$8,400 to US$24,000 in international offers. In Europe, some models of 30–40 kg are listed at approximately €28,950 to €36,750, before taxes, transport, and installation. These values correspond to different equipment and configurations; they do not represent the quoted price of the YR07072.

Frequently Asked Questions

What processing capacity does the YR07072 have?
The technical sheet indicates a capacity of 40–42 kg per batch. The processable amount may vary depending on the type and preparation of the food.

What foods can be lyophilized?
It can be used with vegetables, aquatic products, meats, seasonings, instant beverages, and prepared foods, among other products compatible with lyophilization.

Does the machine automatically configure the entire process?
The equipment has a PLC system, one-button start, and preset standard processes. It also allows for customizing temperature, time, and vacuum curves according to the product's needs.

What electrical supply does it need?
The indicated configuration is 220 V / 50 Hz. The sheet states that it can be customized to 110 V or 380 V; it is advisable to confirm the available voltage before placing the order.

Advantages and Considerations

Among its advantages are its lyophilization area of 3 m², the eight trays, automation via PLC, and the ability to adjust the process. The transparent door facilitates observation of the cycle, while fault diagnostics and protection functions help monitor operation and prevent accidental parameter changes.

As aspects to consider, the equipment requires an electrical installation compatible with a power of 4,500 W and sufficient space for its dimensions and weight. The net weight is 335 kg and the gross packaged weight reaches 439 kg. Additionally, the cycle duration and final result depend on each food and may require testing to define the appropriate load and parameters.

Product Use in the Field

In a small food plant, the operator distributes the prepared product over the eight trays, selects a standard program or adjusts the parameters according to the food, and starts the cycle. The PLC control supervises the process under vacuum, while the cold trap captures the extracted moisture. At the end, the lyophilized product can be packaged in suitable containers to protect it from ambient moisture.

The equipment can be integrated into the production of ingredients for soups, lyophilized fruits and vegetables, instant mixes, or specialty products. Before producing on a commercial scale, it is advisable to validate the result with test batches, as the load, thickness of the pieces, and moisture content influence the cycle.

Recommendations

Install the lyophilizer on a firm surface, with space for ventilation, service access, and movement of packaging. Before connecting it, confirm that the voltage and frequency of the electrical network match the requested configuration. Follow the manual instructions for loading the trays and cleaning the chamber, and record the parameters of each product to reproduce cycles that yield good results.

At the end of each process, clean and dry the surfaces according to the manufacturer's instructions, check the seals, and maintain the vacuum system in proper conditions. To preserve the quality of the product, use containers with a good moisture barrier and define storage according to the processed food.
