Hi, this is not my usual field of expertise so bear with me as I’m definitely not an expert on refrigeration.
I’m in a strange situation where we own a creamery, and we are big enough we out grew the two ice cream machines (Emory Thompson) we have. We all currently have a regular day job, but we’re having a hard time keeping up with production and are often making ice cream after work from 5:30pm until 2 or 3 in the morning. All 3 of us are exhausted… Long story short I want to make ann ice cream machine that will handle larger volumes of ice cream since there is not one on the market in this size range. I need help sizing the refrigeration side of the unit to make sure this is even feasible.
I’d like to use R404 (unless there’s something better for my application)
The mixing chamber of the machine which will be a metal cylinder that the walls cool on in order to cool the churning ice cream. The size is 18” diameter and 34” long cylinder. The ice cream needs to cool down to approximately 25 degrees F from approximately 37 degrees F in a 10-15 minute period.
Is R404 the best refrigerant to use here?
How many feet of tubing would I need to coil around this cylinder? What diameter tubing is best for this coil?
What type and size of expansion device is best?
How much refrigerant would I need in terms of weight?
What type and size compressor is best for this application?
My plan is to use a water cooled condenser and regulate a flow of cold water based on its temperature.
I’ve never designed a refrigeration system from the beginning, I’ve only ever repaired previously functional systems. Thank you in advance!
