Ice cream was originally made using very intensive labor and it often took one individual hours to make. Johnson had invented the hand cranked ice cream churn as a way to make ice cream faster and easier than by hand. [4] The patent number for the Artificial Freezer is US3254A. [5] It was patented on September 9, 1843, and antedated on July 29 ...
Common capacities range from 30 kg (66 lb) to 1,755 kg (3,869 lb). Since the emergence of cube ice machines in the 1970s, they have evolved into a diverse family of ice machines. Cube ice machines are commonly seen as vertical modular devices. The upper part is an evaporator, and the lower part is an ice bin.
John B. Gorrie (October 3, 1803 – June 29, 1855) was a Nevisian-born American physician and scientist, credited as the inventor of mechanical refrigeration. [1] [2]Born on the Island of Nevis in the Leeward Islands of the West Indies to Scottish parents on October 3, 1803, he spent his childhood in South Carolina.
The machine employed a 5 m (16 ft.) flywheel and produced 3,000 kilograms (6,600 lb) of ice per day. In 1856 Harrison went to London where he patented both his process (747 of 1856) and his apparatus (2362 of 1857). [3] Also in 1856, James Harrison, was commissioned by a brewery to build a machine that could cool beer.

Carré ice machines were brought into New Orleans to make up the shortfall in the South, focusing in particular on supplying Southern hospitals. [94] In the post-war years, the number of such plants increased, but once competition from the North recommenced, cheaper natural ice initially made it hard for the manufacturers to make a profit. [95]
Kept insulated, the ice was preserved for cold food storage during warm weather, either on the farm or for delivery to residential and commercial customers with ice boxes. A large ice trade existed in the 19th and early 20th centuries, until mechanical refrigeration displaced it. Due to its harvesting and trade, ice was considered a "crop". [2]
The first cooling systems for food involved ice. [6] Artificial refrigeration began in the mid-1750s, and developed in the early 1800s. [7] In 1834, the first working vapor-compression refrigeration system, using the same technology seen in air conditioners, was built. [8] The first commercial ice-making machine was invented in 1854.
