Another object of the invention is to provide a .triturating machine in which provisions are made .for heating or cooling the material being treated. By this means,various materialswhich may be treatedmore eff ctive y it erat elevated temperatures or under refrigeration can be nan-1 Another object of the invention is to provide a triturating machine in which rotatable blades move across ,animperforate plate having transverse ribs thereon over which thematerial -is caused to pass ,by action of the blades.

.Still another object of the invention is to pro vide a closure plate for a triturating machine in which perforate and imperforate portions are connected end to end. In this construction, the material is treated primarily onthe imper forate Portion of the plate and the perforate portion forms a screen providing .a restricted outlet for the treated material. I V

The above and other objects, advantages and novel features-of the invention will .be apparent from the lfollowing description when read in conne tion w th the a co an n d a in s in which: n

As best seen in Figure 4, the blades are sharpenedalong one edge adjacent their tip portions, as shown at 25, and are relatively square and fiat on their opposite edge portion Thus, by reversing the'direction of rotation, either the sharp ned' or the flat edge of the blades may be m d .t 'l adine ed e- The-open bottom portion vof the casingis adapted to be closed by a closure plate 26, having its edge fitting ,in grooves formed in the sides 10 -I3he plate 26 Iis of arcuate shape, adapted to lie .olo ely a ja en the tin circle o the blades 18.. and b rries on its inn surface a plural ty of axia y extend ng r .21- v s the i s .21 are formed by rectangular ,bars .welded or therwise suita y fasten d to the plat and presenting relatively sharp Ledges.

these spaces may simplybe left open, but it is preferably closed by a screen plate 28 formed with a plurality of screened portions 29 intermediate its edges. The two plates are connected together in order to close any space therebetween by means of a slotted connection, shown as formed of a pair of narrow strips 3| secured to the opposite vedges -oi the plate 26 atits outlet end,:and..projecting beyond the endof the plate to leave an open slot. One edge of the screen plate 28 may be fitted .into this slot as lemons and limes, which may be quickly and effecthe frozen materials are efiectively thawed and mixed with other materials simultaneously.

7 Similarly, for treating heavy materials such as those containing relatively large quantities of "grease or wax,'it may be preferred to utilize a "heating medium inthe jacket. For other ma- ..terials, as for example, certain medicinal prodation, the plate 26 is formed on its outer con- -vex surface with a jacket 32 substantially-cos extensive with the. plate. Adjacent one, end the jacket is formed" with a threadedinturned flange 33 within which a plug is adapted to be screwed; Forv packing the jacket with a cooling material such'as solid: carbon dioxideor the like, the opening 33 may be closedby using a solid plug screw threaded therein. Howeve yjfor circulating the cooling or heating fluidthrough the jacket, a plug of the type shown in'Figure 3 is preferably'employed, and is formed with an inlet-open ingv 35 ,and an' outlet'opening 36 adapted to be Connected to "suitab e c ting conduits. In order that the incomingffluid may cover th tire. jacket, there is preferably provided a hate fle'or deflector 31"overlying the inlet opening 35 todirect fluid entering therethrough'toward theopposite end of the jacket.- In this manner, the fluid is caused't'o circulate'from the'inlet opening substantially throughout the length of the jacket and finally back and out through the In usefof themachinefit has been found that a large variety of materials may effectively be treatedforvarious-purposes.. For example,' in'- tiniate mixtures of dried powders may beiformed in which a small'quantityof one dried powder is uniformly mixed with a much larger quantity of 'aniothe'rij powder. In a like manner, various grea'syor 'waxy substances may be uniformly 'rnixed' with dried, powdered "materials, as for example in the manufacture of various medicinal andcosmetic products. Powders of substantially any desired degree offineness can be obtained by utilizing a s'cre'en' 'ati29' which will pass only a'fine powder, the mixingoperationserving at the same timeto .reduceth'e size of the powder particles.

I have also found that various food products can advantageously be treated on the machine as described above. For example, peanutsmay quickly bereduc'ed to aivery'smooth and uni- 0 form butter by passing them" through the machine either with'or without using a screen at 29; For material of this type, it is preferable to arrange the blade's' idwith' their flat sides at the :carry the material through the machine asrapidly, and act on it a greater number of times dur-' -ing its passage from fthe inletto the outlet. --'-'Other'{ iood materialgwhich may advantageucts which are required to be kept cool, the jacket may'becooled by the use of any desired cooling medium.

' I have used formedicinal purposes. 'ieists have shown that an emulsion of this type may be' formed chine than with the nozzle;v

7 I have also found that various liquid's'inay be homogenized readily and rapidly, in the present" machine. For example, homogenized milk may be produced much more rapidly and much less expensively than with the usual nozzle type ho-f -mogenizer, since no high pressure on the milk is required, nor any highly restricted nozzle through which it must pass. For materials of "this type, the blades are arranged so that their 'leadingkdge," in. order to carry'the' material-.65, V
