Industrial freeze dryer for food 300 kg YR07036

The equipment combines pre-freezing and drying in a split structure to support process efficiency. Its aluminum alloy shelves receive radiant heating on both sides, and the control allows adjusting the drying curve, heating rate, and vacuum level. It includes an industrial touchscreen and manual and automatic modes; the optional LYO-MEGA control system can store operational data, curves, and alarms for traceability.

The cold trap reaches ≤ −60 °C and has an ice collection capacity of at least 450 kg per batch. The specified final vacuum is less than 5 Pa. The loading capacity of 300 kg refers to the product introduced into the equipment per batch; it does not equate to 300 kg of finished product, as the final yield depends on moisture, food type, and operating conditions.

Market Price

As a general reference, the sales listings consulted for industrial lyophilizers around 300 kg show approximate prices ranging from US$34,000 to US$100,000 or more. For example, there are published offers for 300 kg equipment between US$34,000 and US$70,000, and another for US$95,000. These are indicative prices for comparable models; configuration, controls, installation, packaging, and transportation can change the final amount.

The price of the YR07036 must be confirmed through a quotation, indicating the destination country, delivery conditions, and installation requirements. To request it, you can contact the Kalstein team or generate an automatic quote in Kalstein Plus.

Frequently Asked Questions

What quantity can the YR07036 process?
Its indicated loading capacity is 300 kg per batch. The amount of finished product will depend on the initial moisture and the characteristics of the food.

What products can be lyophilized?
The specification includes fruits, vegetables, meats, poultry, eggs, fish, seafood, mushrooms, beverages, soups, and certain extracts or biological products. It is recommended to confirm product compatibility and define process parameters before starting production.

What level of vacuum does it reach?
The technical sheet indicates a final vacuum of less than 5 Pa.

Does the system allow for process automation?
Yes. It can operate in manual or automatic mode. The optional LYO-MEGA system allows recording data, curves, and alarms over a specified period of up to ten years.

Does the 300 kg capacity represent the final production?
Not necessarily. It is the loading capacity per batch. The weight of the finished product decreases according to the water content removed.

Advantages and Considerations

Among its advantages are the ability for large-scale production, the wide shelf area, the ice capture of ≥450 kg per batch, and the adjustable process control. Manual operation facilitates the exploration of parameters for new products; the automatic mode can be used when production recipes are already defined. The data logging option can also help document cycles.

Due to its size and power, it requires a significant initial investment, industrial space, and adequate services: the specification indicates 120 kW of power, chilled water consumption of 60 m³/h, and compressed air supply of 30 L/min at 0.5–0.8 MPa. The lyophilization cycle can vary considerably depending on the food and load, so it is advisable to validate times and results with tests. The specification does not specify weight or packaging, data necessary for planning transport and installation.

Product Use in the Field

In a fruit processing plant, for example, staff prepares and distributes the load on the trays, selects the validated recipe, and executes pre-freezing and vacuum drying. The control of heating and vacuum accompanies moisture removal; upon completion, the product is removed and packaged in an appropriate container for storage. The same work scheme can be adapted to vegetables, prepared foods, meats, or aquatic products, although each product needs its own parameters.

Usage and Maintenance Recommendations

Before acquiring the equipment, confirm that the capacity of 300 kg per batch corresponds to your type of product and the expected load thickness. Also, request a review of the available services in the plant, especially electrical power, chilled water, compressed air, installation space, and access for transport.

To achieve consistent results, conduct tests with the food you will process, record approved recipes, and clean trays and surfaces according to the manufacturer's instructions. Establish a preventive maintenance plan for the refrigeration system, vacuum pumps, sensors, and control components. Request from the supplier the packaging data, net and gross weight, foundation requirements, connections, and installation procedures before organizing the shipment.
