    摘要: The present disclosure provides a system and a method for utilizing corn cobs to jointly produce a premium xylose and a high-end caramel pigment. The system includes a xylose preparation subsystem, an enzymatic hydrolysis subsystem, and a caramel pigment preparation subsystem that are connected to each other through pipelines. The xylose preparation subsystem includes a raw material tank, a pretreatment tank, an acid hydrolysis kettle, a plate and frame filter press device, a filtrate neutralization tank, a nanofiltration membrane separator, an electrodialysis separator, an evaporation concentration tank, a crystallization tank, a centrifugal separator, and a dryer that are connected in sequence through pipelines. The enzymatic hydrolysis subsystem includes a filter residue neutralization tank and an enzymatic hydrolysis reaction kettle connected through pipelines. The caramel pigment preparation subsystem includes a sugar liquid mixing tank, a browning reaction kettle, a flash tank, an ultrafiltration membrane separator, and a wiped film evaporator. The present disclosure not only utilizes hexose resources in corn cob waste residue and pentose resources in xylose mother liquid in a high-value manner, but also obtains high-value-added high-end caramel pigment products, thereby improving the comprehensive utilization value of corn cobs.

    摘要: A method for preventing crystal maltitol from caking in storage, comprises: detecting a temperature and a humidity of a dried crystal maltitol on-line in real time, an on-line temperature and humidity meter being respectively set a sieving and packaging treatment condition, a redrying treatment condition, and an aging treatment condition, conveying the crystal maltitol under appropriate temperature and humidity conditions to perform the sieving and packaging treatment, the redrying treatment and the aging treatment, respectively; detecting a temperature and a humidity of the crystal maltitol after the redrying treatment or the aging treatment, and conveying the crystal maltitol to perform the sieving and packaging treatment, or else continuing to perform the corresponding treatment until the crystal maltitol satisfies the sieving and packaging treatment conditions to perform the sieving and packaging treatment. The present disclosure saves resources, reduces production costs and improves production efficiency.
