Abstract: Roast and ground coffee in the form of high-sheen flakes and having improved extractability is disclosed. A process for preparing flaked roast and ground coffee of high sheen and improved extractability by passing roast and ground coffee through a roll mill operating at differential speeds and temperatures is also disclosed. The process comprises: passing roast and ground coffee through a roll mill wherein a first roll has a peripheral surface speed of 30 ft./min. to 850 ft./min. and a surface temperature of from 0.degree. to 140.degree. F and a second roll has a peripheral surface speed corresponding to from 2 to 8 times that of the first roll and a surface temperature of from 150.degree. to 300.degree. F.; and removing from said roll mill roast and ground flakes of high sheen and extractability.

Abstract: In making dried animal feed from substantially semi-fluid non-mouldable manure from poultry and other domestic animals the non-mouldable manure is converted into a mouldable product by mixing it with already dried manure and then moulding the product into particles of substantially equal size, which are dried by imparting to the particle a fluidizing movement by means of a flowing hot gas in a so-called fluidized bed.A plant for making dried animal feed from substantially semi-fluid non-mouldable manure from poultry and other domestic animals comprises a mixer with inlets for both the non-mouldable manure and already dried manure, a unit disposed after the mixer for moulding the mixed product into particles, and a container with a perforated bottom in which a fluidizing movement is imparted to the particles in a so-called fluidized bed.

Abstract: An instant beverage is made by forming a mixture of an aromatic food condensate and at least about 10% of beverage solubles, freezing and then grinding the mixture to form frozen particles. The frozen particles are mixed with additional cold, dry beverage solubles to form a mixture comprising from about 0.2% to about 15% of frozen particles. This mixture is then warmed to melt the frozen particles and incorporate the aroma and flavor of the condensate in a stable form into the beverage solubles.

Abstract: A novel roasted and ground coffee product having a unique appearance is produced by roasting a first coffee fraction to a first roast color and water quenching said roasted beans to a relatively high moisture level, separately roasting a second coffee fraction to a second, discernibly different roast color and water quenching said roasted beans to a relatively low moisture level. The two roasted coffee bean fractions are then blended together and ground, producing a coffee product having a speckled appearance wherein the average particle size of the high-moisture fraction is at least 300 microns larger than the average particle size of the low-moisture fraction.

Abstract: A percolation process is described wherein it is possible to operate a fixed-capacity percolator set at decreased capacity without experiencing operational difficulties or coffee extract quality loss. The extraction columns of the percolator set are filled with the amount of roasted and ground coffee desired to be extracted and the remainder of the column is filled with an inert packing material.

Abstract: Coffee grinder gas is fixed in a glyceride at relatively high levels by contacting condensed grinder gas frost and the glyceride in a pressure vessel at a temperature which is above the critical temperature of liquid carbon dioxide. The pressure vessel is then slowly vented in order to prevent a drop in temperature to below the critical level.
