PURPOSE: A sprout cultivator is provided to be able to maintain the environment where vegetables such as bean sprout, peanut and lettuce grow at an optimal temperature. CONSTITUTION: A cooling water tank (CT) and a water jet tank (BT) are separately installed outside of a housing (100), and supplied with water through a water pipe (S). A first cooler (C1) is outside of the housing, and lowers the temperature of the cooling water (CW) of the cooling water tank to an appropriate temperature. A first pump (P1) pumps the cooling water, flows to the first cooler via a first return pipe (R1), and returns to the cooling water tank. A second pump (P2) pumps the cooling water, and circulates through a cooling pipe (CP) so as to maintain the inside of the housing to a set temperature. A heater (H) increases the temperature of the water jet (BW) in the water jet tank to an appropriate temperature. A second cooler (C2) lowers the temperature of the water jet to an appropriate temperature. A third pump (P3) pumps the water jet, and drops to a cultivation box (32) through a supply tube (G). A fourth pump (P4) pumps the water jet, flows to the second cooler via a second return pipe (R2), and returns to the water jet tank.본 발명은 하우징(100)의 내부를 설정온도로 유지시키기 위하여 외부에 냉각수통(CT)을 마련하고, 아울러 분사물(BW)의 적정온도를 유지시키기 위하여 외부에 분사수통(BT)을 마련하여 보다 깨끗한 분사물(BW)만이 새싹에 공급토록 하여 각종 세균 등에 의한 오염원을 미연에 방지함으로써 더욱 청결한 새싹을 키울 수 있도록 한 새싹 재배기에 관한 것이다.
