This is followed by conching, where the liquid chocolate is agitated and mixed at controlled temperatures for several hours to refine its texture and enhance its organoleptic properties.
Load Capacity: The load capacity of a motor system represents the ratio of the actual mechanical output power to the nominal rated mechanical power (Prated) [33].
By contrast, Systems 1 and 3 show lower steady-state THDI but experience short-term spikes during startup, which can produce localized voltage dips or transients affecting nearby equipment.
Additionally, Systems 2 and 3 suffer from high harmonic distortion, particularly System 2, and VSDs would further increase harmonic levels, potentially affecting power quality.
It was observed that during 25% of the system’s operating time, the hot water delivered by System 3 exceeds the setpoint by 5°C, leading to significant energy losses and potentially affecting product quality in the production process.

Results found that all the parameters used in this experiment affect the flow rate in the impedance pump.
The interaction with the inertia of the returning flow is an important factor determining the average flow for a closed loop system [4].
An impedance pump may generate a net flow without using a valve and therefore understanding of its characteristics can also be a major factor in developing the design of novel valveless ventricular assist device (VAD).
Any flow system consisting of relevant vessels of different elastic properties, such as the cardiovascular system, exhibit similar characteristics [6].
Experimental setup consist of four parts namely, measurement equipment, mechanical equipment, tubing connection and fluids equipment.

Introduction Silicon carbide are important structure ceramics because of their excellent mechanical properties, such as, high hardness, high strength at high temperatures as well creep and oxidation resistance.
Reaction temperature, carbon addition, holding time and argon flow rate were chosen as four investigated factors.
The orthogonal experiment investigated the effect of three levels about four factors on products.
In addition, the molding pressure of body also affected the content of SiC.
The FexSiy can decrease antiwear and creep-resistant properties [12].

A large number of complex oxides are often characterized by a wide range of significant changes of electrical, magnetic, mechanical, optical and catalytic properties.
Under certain specific conditions, subtle changes of physicochemical properties and environmental factors (eg. temperature or oxygen partial pressure) such materials can also exhibit characteristics of semiconductors, superconductors, ferroelectrics or ferromagnetic materials.
LaCoO3 based perovskites have very interesting electrical magnetic, catalytic and mechanical properties [1-4].
Dopants of other elements such as Ca or Sr may subtly modify these properties.
Neocera’s PEBS-20 electron source with the Pioneer 180 vacuum chamber setup Experimental procedure LaCoO3 based perovskites are known as multifunctional materials with unique electrical, catalytic and mechanical properties described in numerous publications [9, 10].

For example, physical properties such as density, biomass content, compressive strength, and other relations between them can be potential parameters.
In addition, the use of adequate SCMs can improve some properties, e.g., rheology and mechanical, as verified by Caldas et al. (2020a) and Andreola et al. (2019).
It is important to say that a fair comparison among different bio-concretes must be done carefully, especially when they have diverse bio-based content and, consequently, properties.
Therefore, we conclude that the country’s electricity mix severely affects the bio-concretes carbon footprint and the curves’ adjustment.
If thermal properties of the bio-concretes are available, e.g., thermal conductivity, a thermal efficiency indicator can be used.

The Discussion of Rotor Guide Channel Length of Vertical Shaft Impact Crushing Test Machine Wei Guo*,a, Fang Zhaob, Shijian Lic School of Mechanical Engineering, University of Jinan, Jinan250022, China agw420@126.com, bme_zhaof@ujn.edu.cn, clishijian_engineer@163.com Keywords: Testing machine; EDEM; Modeling and simulation; Rotor Abstract.
The result show that speed is important influence factors of granular acceleration and speed of throwing, but excessive speed will not only increase grain stress, but also can make particle fluctuations increased significantly, channel length and the starting position has a significantly influence on particle acceleration levels, the smaller of the channel’s initial distance, the better of the particle acceleration effect, particles thrown speed as the speed rises, the level of volatility is not always to rise.
In addition, its extensive work environment determines its acceleration process of particle has a certain ambiguity, for particle acceleration effect is good or bad will directly affect the production efficiency and product quality.
As a result, many crusher manufacturers and researchers study of particle acceleration effect given enough attention, they set off from the theory, the impact crushing properties of mineral particles were studied[2,3], aim is to understand the dynamic characteristics and predict impact angle and particle size on the result of impact, particle breakage is how to produce and broken form, determine the impact factors impact the results.
In order to improve particle acceleration effect and the rotor speed and other factors on the impact of speed thrown, thinning speed value, increasing 100,300,500,700 and 900r/min speed simulation.

But multi-planar tubular joint cover more intersection junction node and more complex space, its mechanical performance research is far from mature and the previous research is lesser [3-5].
Finite Element Model of Joint is Established Unit Type and Material Properties.
The end constraints of chord and web members were affected on all nodes of end section in the form of node constraint, and the loading were affected on all nodes of web members end section in the form of concentrated force.
Direct factor is that selection of steel pipe node is from engineering design in the real, is not ideal.
However, the influence rule of size effect is above reflected: the size effect is that the ultimate bearing capacity of nodes is affected, but the nominal capacity is not affected with influence of chord wall thickness.

And the split Hopkinson pressure bar (SHPB) has been widely used to determine the dynamic properties of these materials, such as metals, plastics, composites, concrete, and ceramics [1-5].
The stress states in specimen are affected by several factors, e.g., radial inertia effect, axial inertia effect and the friction constrain between the specimen and the pressure bars [11].
The mechanical properties of the bars are: E=200 GPa, ρ=7872 kg/m3.
The mechanical behaviors of specimen are the same as bar.
