The ooooold Tulsa Ice Company plant in downtown Tulsa (built in 1886 and replaced in about 1933) provided ice for over 3000 ice cooled railcars (15 tons each) ("ice-refeers") daily, as well as ICE for cooling 200+ Passenger cars (10-30 tons each) the seven original Tulsa Hospitals and five hotels (each using over 10,000 tons of ice daily) so do the math yourself! They used steam ejection to refrigerate water into ice, by burning natural gas. Thermal Systems Inc. does the same for a dozen buildings downtown by supplying cold water and steam today, but puts out about 2 MILLION times the BTU's per hour as the old ice plant. All of the old hotels except "The Mayo" are long gone, and they all were fitted with Carrier or Gardener-Banks steam heat/refrigeration plants before they were imploded-I watched every one of them being taken down. The ammonia cooling system uses far less energy than steam-ejection, but requires more electricity. The ammonia process is the Byrd's-Erie (Bird's -Eye frozen foods was named in honor of Col. Byrd) system named after Col. Byrd in Cuba and Erie Locomotive Works Boiler Corp. creating cooling for his malaria hospital. Major Carrier created the steam system to cool malaria hospitals during the construction of the Panama Canal, although the Atchison, Topeka and Santa Fe Railway Co. had used steam ejector cooling for it's Pullman cars since the mid-1880's, just not a GRAND scale like cooling thirty THOUSAND hospital beds. NOTE WELL: More men died of disease building the Panama Canal than in ALL WARS since 1700 AD., an ESTIMATED 390 MILLION or two men per shovelful of dirt! The French started the canal and gave-up because of Yellow fever, malaria and Dengue fever from mosquitoes. The number ONE cause of death to humans on Planet Earth today? The mosquito-by a factor of a million. I'm old enough (70) to remember the horse drawn Ice Wagon from "City Ice" delivering ice to our neighbors, the Grey's, across the street .They got a 300 pound block of ice once a week. When I worked at a service station as a 14-18 year-old, we got 150 pounds a day (in summer) from a truck for our water cooler for ice-cold sodas or "POP" as it's called locally. 150 lbs. of ice, 25 lbs. of rock salt, fill the tank with water, turn on the electric pump, toss in pop bottles-in two hours or less you had 29*F soda pop!!! When it's 105* in the shade, reaching in to find a Dr. Pepper made my teeth ache!
I dont know if this is really a health and saftey issue, unless we're talking workplace safety. By the looks of it, this is just making ice blocks for transporting temperature sensitive foods in trucks. The food never really contacts the ice, just its own container: the ice would damage most foods. Either way, the ice is cold enough that not a lot of germs are going to be surviving anyways. Powerful refrigerant compressor tho, that's a lot of ice to freeze.
Freezing does nothing to kill germs, which is why everyone uses autoclaves to sanitize. This is a complete lack of common sense, prevalent in all of these Indo/Asian factories. Its also the reason those countries are so covered in garbage. This would get the factory shut down very quickly in every western country; for the protection of everyone.

All those skuzzy guys are walking around barefoot where the ice is sliding on the floor!! Not very hygienic!! I’ll pass on using any of that ice anytime soon!
This bulk ice type is used more in nonfood, or rather, not in direct contact with food items, such as ice cream freezing vats. This ice is crushed, poured around a sealed stainless cylinder of ice cream, salt added to the ice, and it is peddled on streetside either in a stationary stall or mobile pedal tricycle shop. It is surprisingly effective in keeping the ice cream frozen without electricity or active cooling, and the ice/salt contents never come in contact with the product.
I think, it was indian, or Bangladesh when i see those dudes. Cause they're wearing bottoms like what indian, Bangladesh used to wear. 😂 Or they're workers from India, or Bangladesh? Or Srilanka?
Each batch makes about 20 blocks of solid ice, processed within 5 minutes, excluding freezing process time. It's assumed they freeze them overnight and harvest them in the daytime. These are either watertight stainless steel or aluminum box racks with open top for filling with water and extraction of ice. Below floor level freezer unit must be large capacity and is most likely an Insulated forced air freezer subfloor. You can see the refrigerant lines running on the sides, the pipes covered in silver Insulation. The extraction process is probably to dip the batch in warm water and then the rack is upended on a smooth floor in a controlled manner to avoid breakage and ease processing. One block of ice is probably the same weight in equivalent water volume. Estimated dimensions are 16" x 8" x 36". I CBA to math all that and just call it 100 pounds per block, which equals 1 ton per batch of 20 blocks. So with all the block trays they have in the video all over the floor waiting to be harvested, 700 tons a day is reasonably achievable. Now whether that is profitable or not, I do not know.
