The present invention relates to a distribution system and an item of equipment for treatment of solid material that comprises same, wherein said distribution system comprises a means for transmitting movement that is configured to generate a rotating movement; a distribution element comprising a surface parallel to the feeding means on which at least one rod is arranged, perpendicularly, configured to come into contact with the solid material to be treated; a rotating means which connects the means for transmitting movement to the distribution element, configured to generate a rocking or circular movement; and a means for supporting the distribution element; wherein a first end of the distribution element comprises a means for joining to the rotating means, situated on an axis eccentric to the axis of rotation of said rotating means, and a second end, opposite to the first end, is accommodated on the supporting means.

Disclosed are methodology and apparatus for freezing the exterior crust of products, such as food products, in a manner that does not cause the exterior of the product to adhere to the surface on which it is placed during or after the freezing.

Products in dry powder form are obtained by lyophilization. More particularly, a lyophilization method includes a prior step of cryogeny under pressure of a matrix containing dissolved gas. A powder may be obtained by this method and used in food processing, cosmetics, pharmacy, and human and animal health.
