Controlled atmosphere storage_ Methods for determining the capacity of cold storage

1、 Controlled atmosphere storage_ Tonnage calculation of cold storage:

Active tone_ Tonnage of cold storage=internal volume of cold storage room × Volume utilization coefficient × Unit weight of food

Active tone_ Internal volume of the cold storage cold storage room=inside the cold storage, length × wide × Height (m3)

Pneumatology_ Volume utilization coefficient of cold storage:

500~1000 m3=0.40

1001 ~ 2000 m3 = 0.50

2001~10000 m3=0.55

10001~15000 m3 = 0.60

2、 Active tone_ Unit weight of food in cold storage:

Frozen meat=0.40 t/m3

Frozen fish=0.47t/m3

Fresh fruits and vegetables = 0.23t/m3

Machine made ice=0.75 t/m3

Frozen sheep cavity=0.25t/m3

Bone removal, meat cutting or by-product=0.60 t/m3

Box packed frozen poultry=0.55t/m3

3、 Active tone_ Calculation method of cold storage storage:

1 In the warehousing industry, the calculation formula of the maximum receipt quantity is:

Effective internal volume (m3)=total internal volume (m3) X0.9

Maximum warehousing volume (ton)=total internal volume (m3)/2.5m3

2 Active air conditioning_ Actual maximum warehousing quantity of cold storage

Effective internal volume (m3)=total internal volume (m3) X0.9

Maximum warehousing volume (ton)=total internal volume (m3) X (0.4-0.6)/2.5m3

0.4-0.6 is controlled by air_ The size and storage of the cold storage are determined. (The following is for reference only)

No. 1 2 3 4 5 6 7

Food category Frozen meat Frozen fish Fresh egg Fresh vegetable Fresh fruit Frozen egg Machine made ice

Weight kg/m3 400 470 260 230 230 600 750

3 Daily stock in quantity actually used

In the absence of special designation, the actual daily stock in quantity is calculated as 15% or 30% of the maximum stock in quantity (ton) (generally 30% if less than 100m3).
