Haier posted this Technology CallSeeking for technologies to reduce frozen meat gravy lossFor current refrigerators, meat and frozen foods are stored under low temperatures (-18℃) for longer preservation. However, after certain period, due to temperature fluctuation (caused by the on-and-off actions of the compressor and defrost, etc.) and sweeping of cold air flow (in air cooled refrigerators), frozen meat may lose water. For example, water on meat surface is removed and food cell is pierced through by ice crystals. Once the meat is thawed, there will be a large amount blood and the meat will taste hard or bad. This will have negative impact on meat quality. To further improve frozen food quality, we are now seeking for a new solution that could be applied on refrigerator products.
Haier posted this Technology CallSeeking technologies or solutions for rapid air dryingHaier seeks technologies or approaches that can rapidly dry air and reduce air humidity level. Background Chest freezers can experience frost formation on the internal surfaces. The frost thickness can reach 5-10 mm within 1 week and can affect the heat transfer efficiency and energy consumption. Over time the frost thickness can also reduce the available storage space and cause inconvenience to consumers who must periodically remove the frost. Tests show that the frost layers mainly concentrate on the lower part of the cabinet and its liner with a frost formation rate of 10g per day (the compressor keeps on for 10 minutes and then keeps off for 14 minutes). We are now seeking for technologies or solutions that can rapidly reduce air humidity level when air flow passes.
Haier posted this Technology CallSeeking self-cleaning electric water heatersHaier seeks technologies to allow easy self-cleaning of electric water heaters. Background Residential electric water heaters commonly develop scale inside the holding tank over time. The presence of scale reduces the efficiency and service life of the electric water heaters, and it may also have an adverse impact on health. Standard maintenance for these water heaters consists of a professional cleaning every 3 years and user cleaning every 6 months. The process for cleaning the water heater tank is straightforward, but time-consuming and messy. Haier, a major manufacturer of hot water systems, seeks technology that will allow easy cleaning (removal of scale) of electric water heater tanks. Ideal solutions will sense when scale removal is necessary and automatically self-clean. But solutions that can provide efficient and easy cleaning on demand are also of great interest. Additionally, the structural design of successful technologies is important – scale and other sediment should be easily flushed from the tank to prevent clogging. Additional information: • Electric water heaters have different volumes, including 40L, 50L, 60L and 80L, etc. • The inner tank of the electric water heater is pressurized. The rated water pressure is 0.80Mpa and the municipal tap water pressure is 0.05Mpa; the rated supply voltage is 200V and the rated frequency is 50HZ.
Haier posted this Technology CallSeeking partners with technologies or methods to remove pesticides from fruit and vegetables during storage within a refrigerator.We seek partners with technologies or methods to remove pesticides from fruit and vegetables during storage within a refrigerator. Preference will be given to technologies or approaches that currently have working prototypes that can undergo feasibility, validation or proof of concept over a 3-6month period. Financial support for the proof of concept phase will be negotiated based on specific performance targets agreed between both parties. For selected collaborators Haier may provide access to samples, test equipment and testing facilities. Technologies will need to satisfy manufacturability, material cost and ease of use assessments to progress from the concept stage.
