The industry for slaughtering and processing animals began in Cincinnati, OH in the US in 1845. It was with the invention of refrigerated railway cars in 1878, however, that Chicago was able to achieve the distinction of becoming the center of America's meat processing industry. It is from here that the methods spread worldwide.
Of course, without drying, smoking or curing, cooling only provides limited preservation time so in the US, the first consumer protection laws were established in 1906 to assure hygenic handling. Strict legal regulations were applied to production, storage, processing and preparation of meat and offal products. Machines and components used in the processing are strictly regulated to ensure hygienic handling and cleanability.
NEMO® PUMPS are engineered to meet the EHEDG directives (European Hygienic Equipment Design Group) or the QHD directives (Qualified Hygienic Design). Materials are approved by the FDA (Food and Drug Administration) and BfR (Federal Institute for Risk Assessment). Along with this, NEMO® hygienic and aseptic pumps meet the regulation of the 3-A Sanitary Standards in the US and are certified according to GOST-R (Russian Certificate of Conformity).
While the hygenic and aseptic versions of NEMO® PUMPS are used on the processing side, many are employed on the disposal side as well.
