This creative department provides a low-temperature spray-dried food raw material equipment, which mainly includes: a drying chamber including a top end, a bottom end, and an action space； a spraying member, which includes a receiving groove and at least one spray head, wherein The spraying member is connected to the drying chamber, and its spray head is arranged in the direction of the working space of the drying chamber. A raw material conveying device communicates with the containing tank of the spraying member, so as to transfer the existing food raw material solution. A low-temperature air compressor communicates with the accommodating tank of the spray member, so as to compress and introduce external low-temperature air into the accommodating tank, and can drive the food raw material solution into a spray-like effluent type through high-pressure gas； The nozzle is guided into the working space of the drying chamber by a spray nozzle； a low-temperature nitrogen supply device is connected to the side of the drying chamber, thereby introducing low-temperature nitrogen into the working space to maintain a low-temperature drying state inside the drying chamber, so that the food raw material solution When sprayed into the action space, it can produce a drying effect to separate water and liquid to form powdery food materials； a powder collection device, connected It is located on the side of the drying chamber, so that the powdered food materials are collected and contained therein； by this, the food material solution can be formed into a powder form in a low-temperature drying environment, so as to avoid high temperature destroying the nutrients and activity of the food materials. Practical and progressive.本創作係提供一種低溫噴霧乾燥之食品原料設備，其主要包括：一乾燥室，包括一頂端、一底端及一作用空間；一噴霧構件，包括有一容置槽及至少一噴頭所構成，其中所述噴霧構件係連通設於乾燥室一處，且其噴頭為朝向乾燥室的作用空間之設置型態；一原料輸送裝置，與該噴霧構件之容置槽連通，藉以將既有食品原料溶液導入該容置槽中；一低溫空氣壓縮機，與該噴霧構件之容置槽連通，藉以將外部低溫空氣壓縮並導入容置槽中，而能夠透過高壓氣體驅使食品原料溶液呈噴霧狀出水型態由噴頭導進該乾燥室的作用空間中；一低溫氮氣供應裝置，連通設於乾燥室一側，藉以將低溫氮氣導入
