Cooling for Baking 
Designed, Manufactured and Commissioned by TES Ltd 
Thermal Engineering Systems Ltd has the unique ability to serve all areas of the process cooling and heat transfer food industry.  
 
TES Ltd provides nationwide innovative solutions to the baking industry and working closely with its bakery clients, TES has excelled in the design and manufacture of numerous cooling installations. 
Projects carried out by TES: 
1. Requirements: A potable water cooling system to cool 6,000 litres of water an hour from a summer maximum of 18ºC down to as low as 2ºC to serve high speed dough mixers.  
 
Solution: A cascade system was designed for the refrigeration plant to allow for variable capacity. This modern system was made all in stainless steel with a fully integrated PLC control system and used food safe propylene glycol.

3. Requirements: A cooling system to cool chocolate covered cup cakes in high ambient temperatures.  
 
The solution was to take cold air from the bakery’s filtered air system, pass it through a chilled water to air coil/reheat coil and re-introduce it via an air distribution plenum raised from the ground and wrapped around the cake stacker. An enclosed chimney effect was created around the stacker with 4 fans at the top. Cold air thus being drawn up through the stacker by the fans and discharged at low velocity into the factory roof space, hardening the chocolate topping on its journey.

2. Requirements: A new chiller to be fitted into existing tanks to serve dough mixing system.  
 
Solution: TES offered a single chiller operating with water/propylene glycol and having four stages in 2 separated circuits, giving total flexibility and reliability. The coolant circulating at -5ºC cooling the process mixing water to approximately 1ºC (or better).
