LAB roaster with unlimited performances

TMR 25 model has been specially designed to achieve the desired roasting profile in terms of time, color and flavor thanks to an innovative system that allows to previously draw the roasting curves. Counting on the same technical features of the industrial Modular Roasters, it can roast up to 25 kg/cycle, thus minimizing the waste of energy and good quality coffees. The roasting profiles achieved can be transferred on Industrial roaster without any parameters modifications, having the same results in terms of product properties. It is an essential tool, which allows the customers to analyze and improve the quality of their product and its performance, carry out specific test before starting industrial production.
