Abstract: A device for automatically processing mushrooms of given caliber Cal, the device including conveyor means (10, 20, 30) designed to bring said mushrooms to at least one processing station (100.sub.i) including detection means (110.sub.i) suitable for determining a parameter relating to each mushroom, a processing member (120.sub.i) for processing the mushrooms individually over a given processing distance C.sub.i, and control means (130.sub.i) suitable for bringing the processing member (120.sub.i) into operation after a response time Tr.sub.i and as a function of the parameter determined by said detection means (110.sub.i). According to the invention, said conveyor means include a "receiver" first set of belts (10) designed to receive the mushrooms at a given mean rate D not greater than min[1/Tr.sub.i ] and driven at a speed V.sub.0 not less than Cal.times.D, an "accumulator" second set of belts (20) driven at a speed V.sub.1 selected to be substantially equal to Cal.times.

Abstract: According to the invention, the cutting station also comprises, on the one hand, detection means capable of individually determining the length of the stem of each mushroom and, on the other hand, control means capable of adjusting the relative position of the cutting device and of the mushroom stem as a function of the length of stem determined by the said detection means.

Abstract: The present invention is concerned with a method for the improvement of the technical efficiency and of the quality of tinned mushrooms. This method is characterized by the fact that, in order to avoid blanching, the de-aeration of the mushrooms is achieved by treatment under a partial vacuum combined with an impregnation by means of a saline solution that makes a loss of water by osmosis possible.
