Patent ID: 8683743

Claim:
A grain germinating system for incubating a grain, comprising: a temperature controlling device, comprising: a piping module; and a heat pump module connected to the piping module, wherein the heat pump module comprises a first liquid outlet, a first liquid inlet, a second liquid outlet and a second liquid inlet, the first liquid outlet outputs a high temperature heat exchanging liquid, the first liquid inlet recycles the high temperature heat exchanging liquid, which is flowed through the piping module, the second liquid outlet outputs a low temperature heat exchanging liquid, and the second liquid inlet recycles the low temperature heat exchanging liquid, which is flowed through the piping module; an incubation device used to accommodate the grain and a culture medium, such that the grain germinates in the incubation device, the incubation device connected to the piping module in the temperature controlling device for heat exchanges so as to adjust a temperature of the incubation device; and a drying device connected to the piping module in the temperature controlling device for heat exchanges and generating drying air to dry a germinated grain, which is incubated in the incubation device.
