Abstract
Abstract In a batch method for the heat treatment of particulate solid material, especially food materials, the vessel in which the heat treatment takes place is essentially a jacketed pressure vessel (1) in which the material is tumbled while being heated, and in order to obtain an increase in throughput the solids and cooking liquor are removed to a second vessel (2) after cooling. In the second tumbling vessel there is a reversible strainer (12) which is used in the position illustrated to separate the liquor from the solids and then inverted after withdrawal of the liquor so that they may be blended with a different liquor, such as a sauce, introduced via a line (14).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
A batch method for the heat sterilization treatment of particulate solid food materials, in which a batch of particulate solid material is heated in a rotary heat treatment vessel while the vessel is being rotated to impart a tumbling action to the particles of solid material, the heating being carried out at least partially while the vessel contains substantial quantities of liquid, transferring the solids and liquid under aseptic conditions to a second rotary vessel, separating the solid and liquid phases in the said second vessel and removing the liquid phase, introducing a different liquid to the second vessel and rotating the second vessel to tumble the solids and different liquid to blend them together.
Claim 2
Dependent Claim
115 words
A batch method for the heat sterilization treatment of particulate solid food materials, in which a batch of particulate solid material is heated in a rotary heat treatment vessel while the vessel is being rotated to impart a tumbling action to the particles of solid material, the heating being carried out at least partially while the vessel contains substantial quantities of liquid, transferring the solids and liquid under aseptic conditions to a second rotary vessel, separating the solid and liquid phases in the said second vessel and removing the liquid phase, introducing a different liquid to the second vessel and rotating the second vessel to tumble the solids and different liquid to blend them together.
Claim 3
Dependent Claim
22 words
A batch method as claimed in claim 1, in which after heating, the solid material is cooled in the heat treatment vessel.
Claim 4
Dependent Claim
141 words
A batch method for the heat sterilization treatment of particulate solid food materials, in which a batch of particulate solid material is heated in a rotary heat treatment vessel while the vessel is being rotated to impart a tumbling action to the particles of solid material, the heating being carried out at least partially while the vessel contains substantial quantities of liquid, transferring the solids and liquid under aseptic conditions to a second rotary vessel, separating the solid and liquid phases in the said second vessel and removing the liquid phase, introducing a different liquid to the second vessel, rotating the second vessel to tumble the solids and different liquid to blend them together, and discharging the blend of solids and second liquid from the second vessel under aseptic conditions and then packaging the solids and liquid blend under aseptic conditions.
Claim 5
Dependent Claim
141 words
A batch method for the heat sterilization treatment of particulate solid food materials, in which a batch of particulate solid material is heated in a rotary heat treatment vessel while the vessel is being rotated to impart a tumbling action to the particles of solid material, the heating being carried out at least partially while the vessel contains substantial quantities of liquid, transferring the solids and liquid under aseptic conditions to a second rotary vessel, separating the solid and liquid phases in the said second vessel and removing the liquid phase, introducing a different liquid to the second vessel, rotating the second vessel to tumble the solids and different liquid to blend them together, and discharging the blend of solids and second liquid from the second vessel under aseptic conditions and then packaging the solids and liquid blend under aseptic conditions.
Claim 6
Dependent Claim
156 words
A batch method for the heat sterilization treatment of particulate solid food materials, in which a batch of particulate solid material is heated in a rotary heat treatment vessel while the vessel is being rotated to impart a tumbling action to the particles of solid material, the heating being carried out at least partially while the vessel contains substantial quantities of liquid, transferring the solids and liquid under aseptic conditions to a second rotary vessel, separating the solid and liquid phases in the said second vessel and removing the liquid phase, introducing a different liquid to the second vessel, rotating the second vessel to tumble the solids and different liquid to blend them together, and introducing a second batch of particulate solid material in the rotary heat treatment vessel to be heated at the same time that the separation and blending steps are being carried out on the first batch of material in the second vessel.
Claim 7
Dependent Claim
156 words
A batch method for the heat sterilization treatment of particulate solid food materials, in which a batch of particulate solid material is heated in a rotary heat treatment vessel while the vessel is being rotated to impart a tumbling action to the particles of solid material, the heating being carried out at least partially while the vessel contains substantial quantities of liquid, transferring the solids and liquid under aseptic conditions to a second rotary vessel, separating the solid and liquid phases in the said second vessel and removing the liquid phase, introducing a different liquid to the second vessel, rotating the second vessel to tumble the solids and different liquid to blend them together, and introducing a second batch of particulate solid material in the rotary heat treatment vessel to be heated at the same time that the separation and blending steps are being carried out on the first batch of material in the second vessel.
Claim 8
Dependent Claim
30 words
The method of claim 4, wherein the liquid phase removed from the second vessel is introduced in the rotary heat treatment vessel with the second batch of particulate solid material.
