Blast Durian Cold Storage

Blast cold room for Durian

The advantage of blast-freezing preservation is to ensure that durian meat is peeled off when it is naturally ripe without any additives and is healthy and safe.

Generally, durian is stored in a low-temperature freezer at - 60 C about three hours after landing for quick freezing. After one hour of rapid freezing, durian is stored in a freezer at - 18 C to - 22 C. In this way, the rich and sweet durian can be fully preserved.

Design of Durian cold room

1. -45~-60℃ mainly to use for quick freezing whole durian after picking

2. -35~-45℃: mainly used for quick freezing of processed and clean pulp. Flesh Moving of Durian Fruit after Quick Freezing

3. -18~-25℃: Long-term storage in the freezer is convenient for later production of various durian delicacies.

Pre-cooling process

Durian blast-freezing preservation is a very rigorous technology. After picking, durian must be eaten or frozen within 8 hours. Otherwise, the fruit is easy to ferment naturally and rot after producing a lot of water.

The price of Super Deep low temperature cold storage is generally calculated according to the requirements of capacity and temperature to accumulate the cost of cold storage. Mainly as follow

-45~-60℃ mainly to use to quick freezing whole durian after picking

-35~-45℃: mainly used for quick freezing of processed and clean pulp. Flesh Moving of Durian Fruit after Quick Freezing

-18~-25℃: Long-term storage in the freezer is convenient for later production of various durian delicacies.

 

The advantage of frozen durian

The frozen durian is thawed slightly. It tastes delicate and has an ice-cream taste. Compared with fresh durian, it has a different flavor.

Frozen durian is delicious and healthy on the premise that quick-frozen, freezing in place throughout the whole process, such as temperature does not meet the standard, it will cause bacteria exceeding the standard.

Durian blast cold room is designed to be less than 40 cubic meters compared with other kinds of cold storage, But the requirement is stricter and the cost is higher than that of the general quick-cooling storage project.

Basic information about Durian cold storage

The goods volume (one time)：How many tons of durian blast freeze room need to be input at a time? For example 3 tons, 5 tons? Or what is the design capacity of the durian freezer, 30 cubic meters? 40 cubic meters?

Blast freezing time: How long does the durian freezer design take to freeze 3 tons of goods you put in? For example 8 hours, 10 hours or 12 hours,

Central Temperature of Durian: How many degrees do you require the central temperature of durian pulp to be put into the durian freezer? For example: - 15℃, - 18℃, or -40℃.

Packing way: durian meat or whole durian

Compressor request: Bitzer, Copeland or other brands are available

Durian is a tropical fruit with high nutritional value. In recent years, Thailand, Malaysia, and other countries have begun to use cold storage to preserve durian.

Two-stage compression or cascade refrigeration system is generally used in cryogenic and ultra-cryogenic storage, which can meet the requirements of cryogenic storage temperature and ultra-cryogenic storage temperature ranging from -30℃～-45℃、-45℃～-70℃、-70℃～-105℃

The above is about the design of durian Blast and how long the durian freezer can be stored at - 18 ℃
