A and 30B, the supply of syrup and water does not immediately start even if a supply signal is input, and a predetermined time C (4 in this embodiment).
〜5 seconds) before starting feeding.

As described above, even if a supply signal is input immediately after the start of the compressor 36, syrup and water are not supplied until the compressor 36 is stabilized.
9A, 19B and the water sensor 24 can detect syrup and water.

[0038]

As described in detail above, according to the first aspect of the present invention, when the operation start signal of the compressor is issued during the supply of the liquid frozen dessert material, the start of the compressor is delayed for a predetermined time, Give priority to the supply of frozen dessert ingredients.

Therefore, when the compressor is started, since the frozen dessert raw material is surely introduced into the cooling cylinder, the frozen dessert can be manufactured quickly. Furthermore, even if the installation condition of the ice confectionery apparatus is poor and a voltage drop occurs when the compressor is started, it is possible to reliably detect the liquid ice confectionery raw material. According to the second aspect of the present invention, if the supply of the frozen dessert material is not completed before the operation of the compressor is started with a delay, the supply of the frozen dessert material is performed for a specified time until the operation of the compressor is stabilized. Is stopped, and after the specified time has elapsed, the frozen dessert raw material is supplied again.

Therefore, even if the supply time of the frozen dessert material is long and the specified amount of the frozen dessert material is not introduced into the cooling cylinder by the time the compressor is started, most of the frozen dessert material is introduced into the cooling cylinder. Since the compressor is started, the production of frozen dessert can be performed quickly. Furthermore, even if the installation condition of the frozen dessert manufacturing apparatus is poor and a voltage drop occurs at the time of starting the compressor,
The liquid frozen dessert material can be reliably detected.
