    Abstract: A process and apparatus for fluidized bed operations wherein the fluidized bed includes an upper fluidized zone and a lower fluidized zone, with each of the upper and lower fluidized zones equipped with agitating means therein. Positioned intermediate the upper and lower fluidized zones are a plurality of tubular zones. Substantially parallel to the fluidized zones is a discharge leg positioned to receive fluidized solids from the lower fluidized zone in which the fluidized solids are fluidized in the leg at a level substantially equal to the level of fluidized solids in the upper zone whereby a portion of the solids can be removed from a repositionable discharge means in the discharge leg. The process involved in this invention utilizes a fluidized system for starch drying wherein the moisture content of the starch supplied to the fluidized bed is controlled to a level not exceeding 27% whereby the fluidized bed can be operated at higher temperatures without damaging the starch.

    Abstract translation: 一种用于流化床操作的方法和装置，其中流化床包括上流化区和下流化区，其中每个上流化区和下流化区均配有搅拌装置。 定位在上下流化区的中间是多个管状区。 基本上平行于流化区的排放支路被定位成接收来自下部流化区的流化固体，其中流化固体在腿部流化，水平基本上等于上部区域中的流化固体的水平， 固体可以从放电腿中的可重新定位的排出装置移除。 本发明涉及的方法利用了用于淀粉干燥的流化系统，其中供应到流化床的淀粉的水分含量被控制在不超过27％的水平，由此流化床可以在更高的温度下操作而不损害淀粉。

    Abstract: The water phase from a corn steeping step is evaporated in a multistage evaporator to a steeping concentrate, the steeped corn being divided into an aqueous germ fraction, an aqueous fiber fraction and a gluten suspension which is partly dewatered to an aqueous gluten fraction. Said three fractions are dried to a low water content by heating while subjected to a direct air flow, causing steam-air flows from said fractions. In the drying of said fractions, the air flow is limited to make the enthalpy of the steam-air flows relatively high, and part of the steam-air flows, preferably combined, is fed to one stage of the evaporator, preferably the first stage to which the water phase from the steeping step is fed.

    Abstract translation: 来自玉米浸渍步骤的水相在多级蒸发器中蒸发至浸泡浓缩物，浸渍的玉米被分为含水的胚芽级分，水性纤维级分和部分脱水至谷蛋白级分的谷蛋白悬浮液。 所述三个级分通过加热干燥至低含水量，同时进行直接空气流动，从而使蒸汽 - 空气从所述级分流出。 在所述级分的干燥中，空气流被限制以使蒸汽 - 空气的焓相对较高，并且优选组合的部分蒸汽 - 空气流被输送到蒸发器的一级，优选地是第一级 来自浸渍步骤的水相进料到其上。

    Abstract: Polyurethane foams are prepared by reacting an active hydrogen-containing organic compound with an organic polyisocyanate in the presence of a blowing agent and an amylaceous material which has been stabilized (a) by treating with a stabilizing agent containing an effective amount of an antioxidant capable of inhibiting the formation of oxidation products in the amylaceous material upon exposure to an oxidizing atmosphere or (b) by removing substantially all, or at least a major portion, of the oxidizable materials, particularly fatty acids or fats, from the amylaceous material.

    Abstract: Starch which has been treated with a hydrophilic organic solvent, such as a low molecular weight alcohol, ketone, or the like, and which, as a result, retains relatively large quantities of these solvents, is desolventized by admixing it with a gel retarding salt, and heating the admixture to a temperature above about 150* F. The process is applicable to any type or variety of starch in nongelatinized form; the process does not gelatinize or otherwise affect the properties of the starch.

    Abstract: STARCH WHICH HAS BEEN TREATED WITH A HYDROPHILIC ORGANIC SOLVENT SUCH AS A LOW MOLECULAR WEIGHT ALCOHOL, KETONE, OR THE LIKE, AND WHICH, AS A RESULT, RETAINS RELATIVELY LARGE QUANTITIES OF THE SOLVENT, IS DESOLVENTIZED BY CONTACTING IT WITH A HOT HUMID GAS, SUCH AS, FOR EXAMPLE, STEAM OR MOIST AIR, WHILE MAINTAINING THE STARCH AT A TEMPERATURE OF FROM ABOUT 160*F. TO ABOUT 320*F. AND AT A MOISTURE LEVEL OF FROM ABOUT 1% TO ABOUT 15%. THE PROCESS IS APPLICABLE TO ANY TYPE OR VARIETY OF STARCH, IN EITH NON-GELATINIZED OR PREGELATINIZED FORM; THE PROCESS DOES NOT ALTER OR OTHERWISE AFFECT THE PROPERTIES OF THE STARCH.
