This device is intended for molecular gastronomy that is a subdiscipline of food science (trophology). This direction studies the physicochemical processes during cooking. The basic principles of this science segment were first formulated in 1988 by physicist Nicolas Kurti from Oxford and the French chemist Herve This from INRA. Today, a lot of people are supporters of molecular cuisine. Of course, the market actively offers new technological solutions in this segment. The infrared dehydrator L’equip IR-D5 is one such device.
This model is equipped with two innovative features.
The automatic dehydration function uses humidity sensors to calculate the end time for the heat treatment process. This algorithm also takes into account the drying temperature. The dehydration process ends when the humidity decreases to the set value.
The IR-heating mode is the second innovation of the model. The red spectrum lamp serves as a heating element for creating low-temperature longwave infrared radiation. This radiation is considered absolutely safe for food and human.
The nontransparent plastic door of the dehydrator provides effective heat insulation of the working chamber.
Of course, visual control of the degree of readiness is not available. It’s carried out based on the readings of the sensors. The inner surface of the door is made of stainless steel to increase thermal efficiency. Reflected heat additionally heats the food in the chamber.
The fan and infrared lamp are located on the back of the inner chamber.
Five trays of stainless steel easily withstand the weight of the products and provide very uniform heating due to increased thermal conductivity.
The device works in manual or automatic modes. The first mode requires setting the duration and drying temperature. Automatic mode determines these values based on dehydration values. Switching between modes is done using the Auto / Manual button.
The preset values are 35 degrees and 1 hour. The regulator provides the choice of temperature in manual mode in steps of 1 degree and a time from 1 to 99 hours in steps of 1 hour.
Silicone potholders are designed to safely remove trays from the working chamber.
Energy efficiency is one of the main characteristics of these devices. Testing showed the following values (1 kg of apples for 1 hour of operation):
– 0.08 kWh for 35 degrees (convection);
– 0.05 kWh for 35 degrees with IR heating;
– 0.3 kWh for degrees (convection);
– 0.29 kWh for 70 degrees with IR heating.
The automatic mode showed the following values:
– 3.9 kWh for 3.3 kg of apples with IR heating for 12 hours of operation;
– 1.42 kWh for 1 kg fillets (convection) for 4 hours 50 minutes.
These indicators demonstrate the high energy efficiency of the model.
– stylish design;
– high energy efficiency;
– two dehydration modes using an infrared lamp or traditional convection;
– automatic dehydration mode;
– low noise level;
– high uniformity in automatic mode.
– high price;
– fogging during dehydrating very moist products;
– lack of visual control due to the opaque door.
The wide possibilities of this model are perfectly demonstrated on the video.
