A computer controlled power saving automatic zoned dryer for a printing press has a dryer head facing the substrate travel path, having a multiplicity of IR lamps connected individually or in groups to form a plurality of heating zones running longitudinally and each extending laterally side by side across the substrate travel path. The radiant heat output of each heating zone is controlled separately by means of a control unit connected to a power supply. The control unit individually regulates output of the heating zones. Unneeded zones are turned off to reduce cost of power and conserve energy. A plurality of heat sensors spaced laterally across the substrate path measure the surface temperature of substrate heated areas corresponding to the heating zones being operated and maintain an automatic set point temperature. The temperature of each individual heated area can be regulated automatically by adjusting the output of its heating zone whereby printed substrates having a more even temperature profile are delivered. In an alternate manual mode any zone can be set independently to operate at any percentage of full available power from zero to 100%. Separate high velocity air scrubbers and additional air extraction are used to enhance the total drying effect of the zoned dryer assembly.

A system and method for cooling air includes using a refrigerant cooling system and further using a refrigerant liquefaction subsystem or method that includes using a heat sink cooler (“pre-cooler”) to cool the heat sink coolant before it is used to cool the refrigerant in the condenser. One aspect of the refrigerant liquefaction subsystem may use a water mist, which may be prepared by atomizers, high pressure nozzles, piezo-electric ultrasonic nebulizers, or the like, to cool the heat sink coolant.

Furfurylated wood produced in a two-chamber system in which monomer/oligomer impregnation in an impregnation chamber is followed by successive stages of drying and curing. Physical properties of wood under treatment are measured, recorded and referenced into a database that accumulates wood species data relating to applied temperature and pressure profiles, physical properties and appearance of intermediate and finished samples of wood and also chemical treatment regimes, including soak time and monomer/oligomer concentrations. During drying and curing, monitoring of process parameters, including water removal and/or atmospheric conditions, are used by a controller both to control and determine a state of process completion by comparing recorded data with historically accumulated data or process set point conditions. Physical and/or chemical attributes of finally processed wood are used in an automated control loop to modify, reactively or in real time, applied treatment regimes for specific wood species and wood profiles.

A geothermal desiccant cycle cools and dehumidifies the air in an indoor conditioned space. The return air is split into two streams. One of the streams passes through a desiccant wheel to remove water vapor and then through a cooling coil for sensible cooling from geothermal water. The other stream is heated to increase its capacity to absorb moisture, and then is passed through the desiccant wheel to pick up the moisture transferred from the first stream and regenerate the desiccant. The second air stream, which now has a higher dewpoint temperature, flows through a geothermal cooling coil, for sensible cooling as well as condensation of the moisture. The two air streams are mixed and supplied back to the conditioned space. A regenerative air-air heat exchanger can be used to recover some of the heat used in heating the second air stream.

The invention belongs to the technical field of flower breeding, in particular to a method for doubly improving a marigold genotype by utilizing chromosomes, which is characterized in that male sterile dual-purpose line of a seed or a stem tip of marigold is treated by adopting a colchicine solution so as to enable the number of the chromosomes of the marigold to be doubled, thereby providing a breeding starting material of the improvement of the marigold genotype. The method comprises the following steps of: bud forcing treatment, colchicine doubling treatment, rinsing relief treatment, cultivation management, chromosome ploidy authentication and the like. The preferable treatment is described as follows: applying colchicine solution with concentration of 0.05 percent to marigold germinating seeds and soaking for 3 to 6 hours, and thus, the survival rate of plants is high, and the doubling efficiency also reaches 88.89 percent. The invention can effectively control the environment temperature and humidity when the seeds germinate; the repeatability of a test is high, the operation is convenient and time and labor are saved. The invention is suitable for the improvement of the marigold genotype.

The invention relates to a method for preparing black garlic by liquid state fermentation. In prior art, production and processing methods of the black garlic are long in fermentation process time, the humidity of fermentation workshops is required to be controlled, under the no-sealing condition, influence of pungent smell given out by garlic on air quality is severely bad, a whole garlic is fermented, and relevant reports of fermentation by garlic juice do not exist so far. According to the method, a fresh garlic is peeled, cleaned and smashed to form mashed garlic, water accounts for 50% of the mass of the mashed garlic is added, then the mashed garlic is placed in a polyethylene bag, the bag is sealed, temperature shift fermentation is performed in a fermentation chamber, and after the fermentation is finished, fermented black garlic juice is dehydrated to obtain a black garlic product. The method for preparing the black garlic by the liquid state fermentation has the advantages that the fermentation process is simple, the fermentation time is short, any additive is not added, the industrialized production is facilitated, the fermentation is performed under the sealing condition, undesirable odor given out by sulfide and the like is absent, and thereby the air quality in the work environment is greatly improved.
