Mrs Higgins Oven Fresh Cookies has been baking American style cookies in New Zealand for over 30 years. They use the finest ingredients to make their cookies, with real New Zealand butter, and no preservatives. The cookie company believes it is the ingredients and the production processes they use that set their cookies apart from the rest of the market. For this reason using the right equipment to keep these products and processes consistent is of paramount importance to them.
The Heat and Chill Answer
Mrs Higgins Cookies was moving to new custom designed premises. It was the perfect time to review their equipment. They investigated alternative options for keeping their cookie dough at a consistent temperature. This is particularly important when the dough contains ingredients such as butter that would either be too hard in winter or too soft in summer. The cookie dough temperature needed to be constantly maintained between 18-22°C.
Markus Hasler, from Mrs Higgins Cookies, had contacted HWHP (Hot Water Heat Pumps Ltd) a few years prior and chose to revisit the solution that had previously been presented to them. The system HWHP offered was a Performance Plus heat and chill heat pump water heater and a buffer tank combination that worked together to control the temperature of the water that was circulated in the jacket of the mixing bowl.
