An inline bitumen froth steam heater system including steam injection and static mixing devices is provided. The system heats and de-aerates input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The system is a multistage unit that injects and thoroughly mixes steam with bitumen resulting in output bitumen material having temperature of about 190° F. The system conditions a superheated steam supply to obtain saturated steam at about 300° F. The saturated steam is contacted with bitumen froth flow and mixed in a static mixer stage.

This disclosure describes a simple, low cost method to produce a modular dry mix that can easily be modified and customized to produce a wide range of easy to aerate, no ice cream machine needed, ice cream and frozen dairy and non-dairy desserts and products made by this process. The method relies on successive simultaneous particle size reduction and blending steps without the use of traditional mix drying operations. The formulations produced by this process are modular and allow quick and simple ingredient substitutions to create distinct finished products. The process yields mixes that produce stronger, more stable foams that don't leave an oily mouth feel. The disclosure also includes a formulation and process used to make ice cream, and related frozen dairy and non-dairy desserts at room temperature in one step where the ingredients do not need to be aged, or homogenized, and aeration occurs without the need for simultaneous cooling or freezing. The process allows the end-user to control and vary the texture, freezing rate, melting point and eating qualities of the product without the use of traditional, home or industrial ice cream machines and a product made by this process. A product produced from this mix consists of a (protein-concentrate and emulsifier)—stabilized, protein-based foam created by combining a powder mix with one or a combination of a large range of above freezing temp liquids then immediately whisking the mixture at room temp to a target overrun without pre-aging, and then freezing that product statically till desired hardness is achieved. The main execution of this process involves the use of dry powders that are transported and sold dry and then reconstituted by the end user before they are combined without pre-treatment, freezing homogenization or aging. The manufacturing process offers significant advantages over current dry mix production methods which require significant upfront investment and produce hard to customize mixes. The formulation and finished product making portions of the invention offer significant improvement over existing manufacturing methods for frozen desserts and dessert mixes that require simultaneous freezing and aeration in terms of cost, convenience, customizability, shelf-stability and environmental impact.
