The present invention “Production process of nixtamalized maize flour, nixtamalizing the maize fractions separately without producing nejayote”, considers the integration of the processes: Semi-humid milling of the maize (fractionated degerm), extruding of the maize endosperm and milling-instant dehydration of the different nixtamalized and extruded maize fractions, has as novelty the way in which the nixtamalization process is carried out and the objective is to provide a nixtamalized maize flour production system that reduces the residues from the maize grain and completely eliminating nejayote production.

A plant processing system may include an initial preparation apparatus for treating plant material prior to processing the plant material, and the initial preparation apparatus may be configured to lower a temperature of the plant material from an initial temperature to a lowered temperature. The system may also include a plant processing apparatus configured to process the plant material received from the initial preparation apparatus at approximately the lowered temperature. In some embodiments, the plant processing apparatus may be a plant stripping apparatus configured to detach constituent parts of the plant material from each other. In some embodiments, the plant processing apparatus may be a plant grinding apparatus configured to grind constituent parts of the plant material.

A roller mill (10) for grinding material, an aspirating assembly (23; 23) and a method of retrofitting an existing roller mill. The roller mill (10) contains a grinding space (11, 11) for grinding material, a separating wall (17) separates the grinding space from an aspiration space (21, 21). At least one aspiration opening (13), is formed in the separating wall (17) through which aspiration air can flow due to a pressure difference between the aspiration space and the grinding space. The roller mill (10) has a closing element (14) for opening and closing the aspiration opening (13). The closing element (14) is in or moves into an opening position (O), which opens the aspiration opening (13), when the pressure difference exceeds a threshold value, and is in or moves into a closing position (S), which closes the aspiration opening (13), when the pressure difference falls bellow the threshold value.

The present application relates generally to emulsifiers and methods of production thereof, and specifically to emulsifiers prepared using renewable and/or agricultural products through a physical process. Flour of cereal grains, legumes, or other plant materials contains both protein and carbohydrate, in particular starch. The preparation procedure of flour emulsifier contains physical processing, including but not limited to specifically designed heating, milling, or the combinations of both. Emulsions of lipophilic materials are prepared using flour emulsifiers. The emulsions formed can be further dehydrated using spray drying, drum drying, freeze drying, vacuum drying, or other drying methods. The emulsions prepared using flour emulsifiers as well as their dehydrated products show enhanced stability against physical and chemical deteriorations as compared with those prepared using conventional emulsifiers, such as octenylsuccinate starch and gum arabic.

A method for the reduction and/or removal of pathogenic agents and microorganisms contained in solids, comprising the steps of purification of the starting material to dispose of materials that combine a great size and extreme hardness and malleability; and the adjustment of the humidity degree of the material obtained in step of purification, and the grinding and heating of the material obtained in the step of adjusting the humidity, where the grinding and heating are carried out simultaneously by subjecting the material to a high pressure while at the same time its temperature is increased by means of an increase in the pressure on the material and the friction caused between the material and the grinding means. And A machine to carry out the method, comprising a front chamber for the entrance of the material; a contiguous rear chamber associated with the entrance chamber, by means of which the processed material is expelled; said contiguous rear chamber containing a grinding means that rotates when it is actuated by an engine; and a piston that enters into the front chamber running along said chamber into the rear chamber until it reaches a grinding means, where the grinding means consists of a solid, hard and heavy cylinder associated with a transverse axis, said cylinder being provided with a set of longitudinal slots from base to base that form edges with the cylinder surface.
