Definition of a thawing process • • Unfreeze of meat or other products like fruit, vegetables or fish Temperature controlled process From e. g. -20°C (-4°F) to -1°C (+30°F) Or to a temperature for the following production steps like slicing or cutting © Product Management 2015 www. vemag-anlagenbau. com vertrieb@vemag-anlagenbau. de
Reason for thawing • Nearly 200 mio tons of meat are produced in the world every year • Apart from this about 20% will be frozen • Transport routes / export of meat from Brazil, Denmark, Germany, Canada Shelf life Hygienic requirements Just-in time production Taking advantage of good market prices • • © Product Management 2015 www. vemag-anlagenbau. com vertrieb@vemag-anlagenbau. de
