Pilot Durian Freeze Dryer

This type of pilot durian freeze dryer adopts low temperature heating in the drying process, which can better maintain the durian's nutrient composition and smell.

Features of pilot durian freeze dryer

Freeze-drying end-point test system: It can automatically perform freeze-drying end-point test after the analysis and drying phase is over to ensure that the moisture content of the substance meets the standard requirements (optional).

Vacuum adjustment system: adjust the degree of vacuum during the sublimation and analysis drying process to avoid the problems of special material foaming, bottle blowing and speeding up freeze-drying efficiency (optional).

Pulse backfilling system: three backfilling modes can be selected: slow, medium, and fast, which avoids the problem of effective substances being blown off and lost due to aeration of granular and flocculent substances after freeze-drying (optional).

Automatic drain system: After draining, it is interlocked with the vacuum system to avoid vacuum system failure (optional) caused by forgetting to close the drain valve when used again.

It adopts industrial touch screen, which has good human-computer interaction, easy to understand, and easy operation without manual.

Manual automatic mode selection: manual mode is used to explore the process parameters (strong human intervention), automatic mode is used in the mature stage of the process, one-key operation, simple and convenient.

Production process

• Material selection

Select durians that are of a high caliber, well-matured, and flavorful. Typically, durian cultivars with a strong aroma and sweet flavor, like Mon Thong, are selected.

Cleaning and shelling:

Clean the durian, remove the shell and take out the pulp. After removing the core, cut the durian pulp into blocks or strips of appropriate size for freeze-drying.

• Pre-frozen

First, the chopped durian pieces are pre-frozen in a low-temperature setting, often between -40°C and -60°C, to make sure all of the moisture in the durian pulp is solidified.

• Freeze drying

The frozen durian pieces are put into a freeze dryer and freeze-dried under vacuum. The temperature in this process gradually rises to about 0°C to 20°C, and the water in the durian pulp is directly converted into water vapor through sublimation and discharged, thereby retaining the original form, nutrients and flavor of the durian.

• Package

The durian pulp has a light, crunchy feel after freeze-drying. The product has to be sealed and packaged as soon as possible to avoid it absorbing and regaining moisture at this point, which will compromise its shelf life and flavor.

FAQ

 

 

01.How to choose the right freeze dryer?

Processing volume: Consider the amount of material that needs to be processed at one time.
Product type: Different types of products may require different freeze-drying conditions.
Equipment size: Choose the right equipment according to the size of the site.

02.How long does the freeze drying process take?

The freeze drying process takes between 12 and 48 hours depending on the type of material, thickness, water content, and the specifications of the freeze dryer. Some complex or large-scale freeze drying processes may take longer.

03.How to maintain the freeze dryer?

Maintenance of the freeze dryer includes regular cleaning, checking the working condition of the vacuum pump, replacing seals, testing the operation of the cooling system and other routine equipment maintenance.
