Production line with flow-through feed heating and/or cooling system and heated surface for breeding insects, method for breeding insects and uses thereof

A method for breeding insects, comprising the steps of:

• a) laying a feed at the storage temperature on at least one breeding line (14) adapted for laying feed for breeding insects,
• b) heating and/or cooling the feed for insects laid on at least one breeding line (14) adapted for laying feed for insects thereon by a flow-through feed heating and/or cooling system (1) with a closed flow for heating and/or cooling the feed on the at least one breeding line (14), and
• wherein the flow-through feed heating and/or cooling system (1) includes:
• at least one heating-cooling medium supply circuit (17) and at least one heating-cooling medium return circuit (18) connected to each other, and the heating-cooling medium supply circuit (17) and the heating-cooling medium return circuit (18) are fluidly connected to a heat exchanger (3) for heating/cooling the heating-cooling medium, and the heating-cooling medium supply circuit (17) and the heating-cooling medium return circuit (18) comprise distributors (13) of the heating-cooling medium, and to the heating-cooling medium distributor (13) via a shut-off valve (12) heating-cooling pipes (15) of thermally conductive material are connected for the distribution of heat/cold on the at least one breeding line (14),
• wherein the heating-cooling pipes (15) are arranged parallel to the said at least one breeding line (14) for laying feed for breeding insects thereon,
• wherein the heating-cooling pipes (15) of thermally conductive material are arranged along the at least one breeding line (14) for rearing insects and are arranged in at least two rows parallel to each other, wherein the heating-cooling medium supply circuit (17) and the heating-cooling medium return circuit (18) are connected via a three-way valve (2),
• wherein the rearing and/or breeding of insects and/or larval forms of insects concern insects of the orders Coleoptera and/or Diptera.

A flow-through feed heating and/or cooling system with a closed flow, comprising:

• wherein the heating-cooling pipes (15) of thermally conductive material for distribution of heat/cooling on the breeding line (14) are arranged parallel to an autonomous conveyor belt (19) said at least one breeding line (14) for laying feed for breeding insects thereon,
• wherein the heating-cooling pipes (15) of thermally conductive material are arranged along the breeding line (14) for rearing insects and are arranged in at least two rows parallel to each other,
• wherein the heating-cooling medium supply circuit (17) and the heating-cooling medium return circuit (18) are connected via a three-way valve (2),
• wherein the rearing and/or breeding of insects and/or larval forms of insects concern insects of the orders Coleoptera and/or Diptera;
• and
• wherein the heating-cooling pipes (15) are arranged on and/or under the conveyor belt (19) of the breeding line (14) and form at least two rows of heating-cooling pipes (15) spaced from each other, by 20 cm.
