Freezer Capacity Selection Guide


Refrigerators, like chiller , are collectively called plastic auxiliary machines. For customers who buy refrigerators, the most troublesome thing is the choice of refrigerator capacity. This chapter will explain the difficulty of refrigerator capacity selection in detail. The choice of freezer capacity is mainly explained by two aspects below!

First, Q (freezing capacity Kcal / H) = Q1 + Q2
Q1 (Kcal / H of raw material heat into the mold) = W (Weight of raw material injected into the mold per hour KG) × C × (T1-T2) × S (safety factor 1.5 ~ 2)
T1 Temperature of the raw material in the tube; T2 Temperature when the finished product is taken out of the mold
Q2 Heat generated by hot runner Kcal / H

Second, the speed algorithm (not applicable with hot runner)
1RT = 7 ~ 8 OZ 1OZ = 28.3g (including safety factor)
1RT = 3024Kcal / H = 12000BTU / H = 3.751KW
1KW = 860 Kcal / H 1 Kcal = 3.97BTU

In fact, the choice of refrigerator capacity is to know how to calculate it. When you know the actual situation of your own mechanical equipment, you can calculate the refrigerator capacity that meets your requirements according to the above two calculation methods. Of course, in practical applications, you also need to take a long-term view. Considering whether there is a possibility of improvement in the near future, whether you need to buy a refrigerator with a slightly higher capacity to meet the needs of future upgrades, so you can choose I bought a very suitable freezer equipment!
