Apparatus for pelletizing hay comprises an anvil mechanism 43 and a rotor 29 which compresses the hay, supplied through a feed conduit 32 from a pick-up device 21, to form pellets P the anvil mechanism 43 being retractable, Fig. 3. When the force of compression exerted by the rotor is great enough to overcome the force of a resilient member 70 urging the member 56 of the anvil mechanism 43 upwards. The anvil member 56 and an L-shaped member 50 are both pivoted on a cross member 44, Fig. 8, the member 56 having yoke members 57 at the upper end of which are half trunnions 59 engaging in milled out parts of the cross H member 44 when the anvil is in its raised position. As the member 56 is forced down by the pressure from the rotor 29, the trunnions 59 disengage and trigger elements, Fig. 12 (not shown), at the lower end of the member 50 release a latch 60 thereby allowing the members 50 and 56 to pivot outwards. The rotor 29 has a shear blade 42 co-operating with a fixed blade 46. The hay is compressed within grooves, Fig. 7 (not shown), in the rotor which are angularly offset from one another. The grooves may be of various shapes in cross-section, Figs. 22-25 (not shown): The anvil may form part of a toggle mechanism collapsible under a predetermined pressure, Figs. 26-27 (not shown). The pellets may pass through a transfer case before they are discharged.

Abstract: A process for purifying amylose comprises forming a solution of impure amylose in water, treating the solution with a water-insoluble, amylose-inert, sorbent filter aid, separating the filter acid from the solution, and recovering the amylose from the separated solution.  The amylose may be amylose resulting from the fractionation of starch, whole starch composed of at least 50% amylose derived from e.g. highamylose corn, degraded amylose produced by hydrolyses or hydrolytic oxidation or amylose derivatives e.g. hydroxyethyl amylose.  Specified filter aids are diatomaceous earths, fibrous asbestos, fibrous wood cellulose, activated carbon, and clays.  The amylose solution may be formed by heating amylose and water to 150 DEG F. or above, e.g. 250 DEG F.-350 DEG F. for 1-30 minutes, suitably by mixing an amylose-water mixture with high-pressure steam, or by using an autoclave or a coiled heat-exchanger.  The solution may be made in presence of the filter and e.g. 1-15% by weight based on the amylose, the filter aid then being separated by filtration or centrifugation, or the solution may be passed through a bed of filter-aid.  The purified amylose may be recovered by spray- or roll-drying, or by precipitation with an organic water-miscible liquid.
